Finding a tutor can be really stressful. You rely on reviews from other students and hope that one clicks. Well, trust this review because William A is the "real deal." I was having a very difficult time in my Statistic Class and needed help understanding some assignments and then there was the review. His knowledge in Statistics is amazing and he takes the time to answer your questions so that you understand the problems.
He makes you feel comfortable and will explain things to you step by step. I am so thankful to William for helping me through this course.
William (Bill) goes above and beyond every time we meet. He's patient, kind, and explains things well. He's willing to explain things again and go over things repeatedly if I don't understand, or need a refresher. He is willing to look at tests/homework on his own time and emails me notes of what's right, what's wrong, etc. I am really impressed with Bill. I am so glad I choose him as my stats tutor.
He made everything so easy to understand and is really knowledgeable. Very worth it and he is one of the least expensive tutors!
He taught me how to get a grip on fractions and decimals that I couldn’t in the classroom. Definitely the best math tutor I’ve ever had. I would highly recommend him because he can connect to you easily.
HE THOUGHT ME HOW TO INTERPRET THE P-VALE IN REGARDS TO LEVEL OF SIGNIFICANCE, HE THOUGHT ME HOW TO BREAKDOWN STATISTICAL INFORMATION IN AN ARTICLE, HE THOUGHT ME HOW TO PLOT STATISTICAL DATA IN EXCEL
Bill is a very patient and friendly tutor. He has been really good at getting my son up to speed in math. He pushes him to work hard. This is a good fit. I would definitely recommend him.
William was patient and was able to teach my daughter techniques to get the right answers faster. He went over materials she was studying in class to help prepare for her test.
Bill is a great guy and is working with me to prepare for my masters program. The first session went great and I am looking forward to more. We are going to brush up on algebra one, basic and then he is going to teach me advanced statistics.
I really struggle with statistics so it's great to have an outside voice that takes the time to explain what I'm not understanding and help me develop shortcuts to better remember the material.
Very patient and dedicated. Math is his passion and he makes the student think which is a great quality.
My son enjoys his lessons and math is no longer a burden.
Very accommodating...met on my time and location. Knows the material well and willing to work through problems step by step from start to end. Knows how to break down the subject matter to a level that is easily explained and understood.
Bill helped my daughter review some Algebra 2 concepts and when they had finished he also went over some SAT math problems that had her stumped. She found him very patient and able to provide explanations that were clear and helpful. She really seemed to enjoy her lesson with him.
His enthusiasm for finance was infectious. He is knowledgeable with excel and was able to teach me how to use this powerful tool. His is thoroughly knowledgeable in the subject matter.
I highly recommend William as a finance tutor. He taught me how to use excel when solving finance problems and explained the time value of money topic in a way I could easily understand it. Very good tutor!
William is an outstanding tutor. He helped me a lot. William explained some concepts that I was really struggling with. I have a firmer grasp now on the course material. He is a great guy. Thank you.
Thanks for all your insights! I would recommend William as a tutor. Very knowledgeable and an excellent teacher. He is also very accommodating with his time. I gave him a 5 star rating.
Bill is an extremely smart and personable tutor. He breaks down each problem one step at a time and explains them in an understandable way. His patience, great personality, and knowledge of the subject has made me look forward to meeting him each week to work on a subject I've long struggled with.
Honors math classes at the high school level are relatively "self taught"-the teacher teaches you a concept & you teach yourself the rest. My sophomore son doesn't like to ask for help but was clearly struggling and his first lesson with Bill went great! It gave him more confidence in math this week and his grade is already coming up.
Bill walked me through corp finance topics and helped connect my math to applications. This of course was basic session and hope to learn more from Bill in the near future.
Reviewed and explained many topics for AP Stats exams in an understandable way. Pleasure working him for his flexibility. Bill has lot of knowledge in Statistics.
William is very knowledgeable about finance and was able to help me work through ratios and assignments that were pretty new to me in my Masters program. Highly recommend as he has great sense of humor to go along with all that knowledge. I have already scheduled future sessions as well!
Helping my son with Statistics and making big impact on his confidence with Stats and I can see the immediate impact on his grade. Thank you!
Bill is a great tutor! He took me through my homework step-by-step, which is important for me because I need that approach to understand and be successful in the class. I'm so glad I found him because I had met with two other tutors through another tutoring company and I left those sessions more confused and defeated. I'm really looking forward to our future sessions together! He is also extremely patient. If you need a lot of time to work through problems, Bill is the tutor to help you.
I hired William to help with my statistics class. I took it over a decade ago, but found myself spending tons of hours studying to get a concept or stats question. He was like a human calculator, but also very patient. I would highly reccomend him to anyone. Very effective and flexible to your learning style.
Mr. A's clear, careful explanations were very helpful for my daughter who has been struggling with Algebra 2 concepts. Will be requesting more tutoring from him soon!
William has helped me get to the insights of Economics. He has helped me understand marginal rate of returns, Supply and demand curve, etc. I even learned how to access some new skills on excel.
As I said, Bill is extremely competent in tutoring statistics & he is patient & kind. He is making sense of statistics for me.
Great tutor extremely knowledgeable and makes and the material very easy to understand. William is a an A number 1 tutor. He is also a great person to talk to. i highly recommend him to anyone..
I am taking an online Statistics course and felt lost. William was so helpful and easy to work with. He is very intelligent, and his years as a professor are obvious in his teaching style and knowledge base! Highly recommend!
I would give him 10 stars if I could. Very knowledgeable and knows how and what to teach. I tried other tutors from this site, but he is the best.
William helped me with a math lesson that I struggled with for the entire weekend. He helped to ease the anxiety I was feeling about Math.
Bill worked with Stephanie on semester review leading into finals week. They had a very productive and inspiring session.
Met with Bill for a few hours to discuss Finance HW. He did a great job explaining things and had the patience when a topic needed a little more time to sink in. Would consider hiring him again.
Bill has a confidence and ease with the finance material that is infectious. An excellent resource. 5 star and highly recommended
My son enjoys working with William. He is accommodating and very helpful. I definitely recommend William, he is available on short notice which is nice when my son needs homework help.
I was in need of immediate assistance with my statistics course and I luckily came across William's profile. He responded to me right away and we scheduled our first lesson, which turned out to be very fruitful. William possesses extensive statistical knowledge and the ability to clearly explain discussed issues. With his help, I was able to grasp the concepts that seemed impossible. I am grateful for his help and I can definitely recommend him!
He is tutoring my son in Pre-calculus (College Algebra) he is awesome. He went from failing a class to definitely passing with a B. He is such an excellent tutor that I would happily recommend him to anyone. He knows a lot of math and he's good at explaining it. He is great!!
My daughter had a very short term, intensive need for statistics tutoring and William was up to the task. He's very professional, personable and reasonable. I highly recommend him.
Bill is very professional, experienced, positive, honest, and responds quickly. He does a quick assessment of what your son/daughter is missing to be successful. My son, a high school senior, is being tutored in statistics.
I worked with William A. for the first time last week, and he was awesome. He was patient and made sure that I understood the materials we were covering.
I highly recommend using him as a tutor.
You were able to build my son's confidence quickly. My son is much more optimistic about his Statistics homework. Finals are in a month so let's keep this going!
Adding to my comments 4 months later - He earned a 4 on his AP Stats exam. He could not have done it without you!
Bill has tutored my son for Algebra 2 and Precalculus. I have been very pleased with his patience, thoroughness, and willingness to go the extra mile to help my son understand the concepts. Highly recommended.
Unfortunately, I did not rate every lesson session but would give Bill 5 stars for all sessions. Bill is an excellent tutor in all aspects as he truly cares about his students and does all he can to help them do well. He even let my daughter borrow his calculator for her AP Statistics Exam, which was extremely generous of him to do so. He is extremely responsive to all communications and very flexible with his schedule to accommodate a student's needs. I should highlight that at the end of the day it is up to the student to put forth their maximum effort to learn the material; however, Bill will do all in his power to provide all the tools and proper tutoring to help the student.
In terms of statistics, Bill not only has extensive classroom teaching experience through college as he teaches at Northwestern, but also has the actual work experience wherein he can relate the material to help a student understand realistic applications. Bill also has the proper disposition and appears to love teaching students of all levels - particularly those who are serious about doing their best - as he makes himself readily available whenever necessary. My daughter interacted very well with Bill and truly enjoyed working with him because he was very kind and extremely helpful to her. This review is not any different than the other reviews written for Bill in that all consider him to be an EXCELLENT tutor. We can't thank Bill enough for his efforts and results derived in helping my daughter do well in her AP class as well as her AP Exam.
We have and will continue to strongly recommend Bill as a tutor for any student, as he is not only a true professional, but a great person!!! Thank you, Bill.
Bill is an outstanding tutor. He is very knowledgeable in all areas of finance which is where he helps me currently. I highly recommend Bill to any one aspiring to be successful. Thank you Bill for all you do!
How would I describe William A.? I would say, Mr A. is definitely a seasoned instructor. That is, Mr A. was always positive, punctual and seemed to take a genuine interest in my overall grasp of advanced managerial finance problems. Prior to follow up one-on-one sessions, Mr A. always reminded me to take practice quizzes and study hard in order to get more value out of the subject. Mr. A. always seemed to enjoy helping me find solutions to unique challenges presented in my homework problems. In so doing, he demonstrated a solid understanding of a multitude of finance problems and the logical solutions therein, and I learned a good deal.
To that end, I would highly recommend and welcome Mr. A’s tutoring services straight away in the future.
William is a great tutor. He's very patient and he's always on time. It shows that he's not doing this for the money but he truly wants you to learn. I will definitely use him for Statistics next semester.
Very knowledgeable, patient, and is very good with explaining. It was really hard to find someone to help with Statistics and we are very glad to have found this excellent tutor.
When I got in contact with Bill for my Biological Statistics course, I had failed my first homework assignment and was fearing failing the course. With his help, I not only aced every homework assignment but passed my class with flying colors. He was the most professional tutor I've had, never showing up late and always coming prepared. He was patient, funny, and easy to understand. I looked forward to our meetings every week because i walked away feeling more confident with my abilities. Simply put, you will not find a better tutor on this site!!
Mr. A. is a great tutor. My daughter is very pleased with the way Mr. A. walks her through each lesson. We couldn't have ask for a better tutor.
Bill and I met to discuss the sample size scenario I'm facing with work. I probably rambled for a while, but he was patient and listened. When we got down to enough detail he saw what I was after. He said he would need to think about it and write back, which he did within a day or two. The result was not only that my real world dilemma has a plan of attack, but that he provided a formula (with his own personal explanation in usage). This enabled me to work the numbers through from a variety of angles and assumptions. It was nice to feel the light turn on when seeing his response. Very informative.
I very much appreciate that Bill took the time to explain things in writing. Not many do that since it's so easy to copy and paste these days.
Will without a doubt use him when I'm stuck again!
I really learned a lot during the lesson - just what the doctor ordered! William was on time, ready to work and clarified all my questions. Makes life with Statistics class so much easier. I would recommend him any time.
Bill is an answer to our prayers. Not only is he extremely qualified to help with Statistics but he is great at explaining the material in a way that is easily understood. This was our first session but we've already planned to move ahead. So far, so great!
Before I found Bill on WyzAnt, I had been with a "math" tutor who was charging me $50 an hour and didn't know crap about Statistics. Well thank God for WyzAnt bringing me to Bill, because he saved the day. He contacted me back the same night I reached out to him,and had immediate availability. Not only was I able to finish my Statistics homework just in the nick of time, but I was actually able to understand it as well. Thanks for all your help Bill; YOU ROCK!
Am learning due to his patience and well explained techniques!!! Thank you....
In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.
I started off my college career as a math major at Washington University in St. Louis. I am very good at algebra and can generally be helpful to those students who are highly motivated to improve their skills in this area.
I have taken many math courses in my academic career, and I have helped many students get through algebra related topics. However, I am at my best with highly motivated students who seriously want to learn the subject matter.
I have taught many finance course at Northwestern University's School for Continuing Studies since September 1989 as an adjunct lecturer. I currently (at various times throughout the academic year) teach courses in the introduction to finance using M.S. Excel, investment theory, financial institutions and markets, and corporate finance. Many students with bachelor degrees (some with PhDs) have taken my courses. I have tutored many students, including graduate students, in this subject matter.
I taught many Finite Mathematics courses at Lewis University. Many of the subjects in Finite Math overlap subjects covered in pre-calculus (e.g., linear equations, systems of linear equations, matrix algebra and the Gauss-Jordan method of solving a system of linear equations). Other topics covered in Finite Mathematics includes probability and statistics, which I have taught numerous time at various universities throughout the Chicagoland area. In Finite Math, there is heavy emphasis on business applications, and I have significant experience as a quantitative analyst in various positions in my business career. I also teach the use of matrix algebra and to solve systems of linear equations in my Investment Theory course at Northwestern University.
I started off my college career as a math major. Although that was a long time ago, I have helped several students with their pre-calculus courses. The precalculus student that I helped just last academic year went from getting Cs and Bs in her tests to As. She got an "A" in her last course, and she was extremely happy with the results. Since then, I have continued reviewing pre-calculus material and I expect to do so for a long time - it is a subject I enjoy a great deal. I am now working on learning how to use the graphing calculator (TI-84) for pre-calculus problems. I prefer that students send me copies of the problems that they are having difficulty with before we meet, so that their time and money is not wasted.
I have earned credit for more than twenty courses in probability and statistics, at both the undergraduate and graduate levels. In addition, I worked for more than thirty years as an actuary, where I frequently used probability concepts in pricing various life insurance policies. For these reasons, I believe that I can help you understand how to solve your probability problems.
I have helped various students prepare for their SAT math test by discussing with them solutions to problems they may have had difficulty with in working sample exams available through a multiple number of published sources.
I have two degrees with majors in statistics - one a BSBA from UIC and the other an MBA from the University of Chicago. Altogether, I have taken more than 20 courses in statistics at both the undergraduate and graduate level. One of the courses, in econometrics, was at the PhD level. I have used statistical software for these courses, but I am most comfortable with use of either M.S. Excel or Minitab. I am not proficient at the use of SPSS, although I have used it somewhat. If you need heavy use of SPSS in your course, it would be best if you found another tutor who is much more familiar with that than I. For help in pure statistics at the introductory level, I know my stuff.
As mentioned earlier, I have helped many with their trig courses. Usually, the course is part of a Orr-calculus. course where the first part of the course focuses on just trig.
