"Excellent tutor, responsive, and extremely knowledgeable"
- Jacqueline (Jackie), Wheaton, IL on 5/28/14
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.
"Amazing! Responsive, knowledgeable, patient!"

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.

"Positive, Patient and Professional Finance Tutor!"
- C., Warrenville, IL on 3/1/14
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.
"Awesome tutor!!!!! "

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 good tutor"
- Melinda, Aurora, IL on 10/29/13
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.
"Best Tutor by far!!!"
- Carolyn, Wheaton, IL on 1/24/13
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.
"Good listener, exceptional followup, very pleased"
- Dave, Naperville, IL on 4/5/12
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!
"Very knowledgeable "
- Andrea, Naperville, IL on 10/29/11
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.
- E., Wheaton, IL on 10/18/11
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!
