Bosko is approved to conduct lessons through Wyzant Online. Wyzant Online allows students and tutors to work remotely via video, audio, and collaborative whiteboard tools. For more information about how online tutoring works, check out Wyzant Online.

If you’re interested in online lessons, message Bosko to get started.

From the moment Bosko began working with our son, we could tell his style of teaching would work. Our son was struggling with several concepts in Calculus AB and Bosko’s ability to explain and breakdown the concept into something that was easily understood was unprecedented.

In our first (and only session so far) Bosko gave our son the tools to master a problem/concept that normally took him 30 minutes to solve, to easily solving it in under a minute. That’s nothing short of a miracle. Bosko’s enthusiasm is contagious and a much needed breath of fresh air.

Our son is a sophomore and he wants to go to an Ivy. Okay, so good for him. We live in a competitive world and like the old commercial “...you never get a second chance to make a first impression.” Right or wrong, as parents, we’re trying to prepare our children to succeed in that world however we can.

There are tons of Tutoring Services and independent tutors claiming they can deliver the goods. We’ve used most of them and this may or may not be off topic of this review, but I believe Bosko could actually help get our son into an Ivy. Yep, that’s a bold statement. But this family believes it's true and Bosko is absolutely is worthy of it.

Great job, Bosko! Keep sharing your gifts! The world will be a better off for it.

This is my son's second tutoring with Bosko and he has nothing but good things to say about him. Bosko explains the course that my son can understand better than when he is in his classroom. Definitely will be tutored by Bosko on a weekly basis.

I am in AP Calculus and LOST. Bosko explains principles in my language and works with me until I fully understand what is happening. I do not know what I would do without his tutoring.

After one lesson, my daughter got A's on both her make up geometry test and her mid term!! Thanks for being so accommodating and making the work so understandable to her.

My daughter needed assistance with her Algebra 2 Honors class and selected Bosko from his online ratings. We found him to be an excellent tutor and will definitely be using his services in the future.

Bosko was prompt and prepared. My son says he learned a lot and that Bosko raised his level of comprehension and confidence.

Bosko is an excellent tutor. He is energetic and motivated. My son thinks he is very good, his friend has been tutored by him for years! Will use again and again!

Bosko worked with my 12 year old son in Algebra. He made my son feel comfortable and actually motivated to do the math.

Bosko was available for a very last minute and very late night appointment to help my daughter prepare for a test the next morning in statistics. He helped her at 11PM over Skype and was able to help her understand everything she was struggling with. She really liked his teaching style and felt comfortable going to take her test the next day. We have used many tutors before but he is by far the best. He knew how to help her with everything she asked and made it very easy to understand. We are very thankful for his willingness to help her at such short notice and such a late hour. We will absolutely be using him more throughout this semester of math!

I had Bosko as my GRE tutor for some sessions. I had access to online materials. One of them was "quiz bank". That generates random questions on specific topics in GRE that I choose. So sometimes I can't figure out the solution nor others' explanation.

I showed those questions to Bosko and he was able to explain them to me step by step and he was patient with me.

Before I met Bosko, I got 140 in the quantitave section 3 times in a row. But after that I got 150 and got accepted at Stevens Institute of Technology.

Bosko is tutoring my daughter in act math currently and we hope to have him tutor her in calculus during the school year. He is amazing! He is a great teacher, knows his material very well, has a great personality and relates well to to my daughter. We feel very grateful that we came across such an amazing instructor!

Very passionate about math and very knowledgeable about Trig especially. I definitely recommend everyone and any grade level to go to Bosko. He's patient and helped me excel in my college course which can get pretty difficult. Great tutor.

Bosco has the rare gift of communicating math and physics topics in a very easy to grasp manner that gives his students the knowledge and confidence to tackle any problem. He is not only knowledgeable and experienced, but also exudes positive energy. Highly recommended 10 stars!

My son is a junior in high school and needed some extra help with Calculus 150 and SAT Math 2 subject tests. Bosko was able to help my son understand the concepts that he was having difficultly with and move forward in the class as well as have a firm foundation for his SAT tests. He was patient, understood the material, and his schedule was always flexible. He is a fantastic tutor. I would strongly recommend him to anyone who needs a tutor. Thank you Bosko!

Bosko came well prepared. He taught my son well and left him with some helpful notes. We will definitely use him next time.

Bosko helped my daughter understand the concepts that she was struggling with. I was very happy with how he would leave her with a list of things to work on until her next session. That set her up to work on her own between tutoring appointments. He was always easy to reach and he responded to our emails very quickly. I highly recommend him.

Bosko did such an excellent job with my son! My son was getting a D in intermediate algebra with no hope of passing until we found Bosko. He's professional and efficient..worked for hours with my son before his finals. And low and behold my son passed the class with a solid C!! Thank you for helping my son and saving him from taking summer school! We will continue to use Bosko in the future..Highly recommended!

Bosko has been an excellent Calculus tutor. He is patient, communicates well and gets along very well with students. He has a positive disposition and a calming personality. I would recommend Bosko to any parent seeking to help with their child's studies.

Bosko has really helped my child excel in math. He has helped him review all of Algebra, and has helped him prepare for the SAT. He knows an incredible amount of math, and is very good at explaining the difficult questions my son does not understand. All in all, Bosko is a great math tutor who is perfect for kids of all ages.

I've been with Bosko for awhile now and he really works with your pace. I'm a visual learner when it comes to math and he'll work around your stregnths! Bosko is also extremely smart, I had some chemistry work to be done and he even helped me with that!

Bosko was able to provide solutions to the most difficult problems that stumped my brightest colleagues and explained the steps thoroughly.

Bosko really helped my son get through Pre-Calculus Honors. Fantastic instructor, knowledgeable and really connected with the "too cool for school" son.

Bosko gave me new ideas and explanations for what I was doing in Pre calc. He helped me conquer every problem I needed help with. In addition, he was very understanding if I were confused and gave me his full attention to make sure I understood it.

Bosko was able to assess quickly where my daughter was at and was able to show her some things that helped her grasp the concepts quickly.

My son is struggling in Algebra and it is definitely not his best subject but Bosko has made it very easy to understand and less frustrating. My son wishes Bosko was his teacher.

My boys really like him. He's very patient and teaches in a way they can understand. They haven't run across a problem he couldn't help him with. Very happy we found him!

Bosko is tutoring my child in honors geometry. We are very happy with him and perhaps more importantly my kid likes the sessions. He is easy to book and flexible if we need him to stay a little longer to finish. He is a conscientious person.

I would definitely recommend Bosko! I have a learning disability with math (Dyscalculia) and needed a very detailed math refresher. Bosko took the time to look at my math tests and analyze areas that needed fine tuning; from there, he designed a lesson plan in order to strengthen my weaknesses and adopt a new style that is easy for me to comprehend. Yes, I have to practice a lot of things extensively and it wasn't easy. Honestly, I really do recommend college students to him because he is so patient and is dedicated to help students like me. Thank you, Bosko!

New update: You must get Bosko as your Math tutor! Last Spring semester, my grades increased to B average and I'm grasping the concepts much quicker. His style of tutoring is phenomenal and you'll pass as long as you practice. Bosko knows if you're practicing or not and you must be committed to do the work. I really do appreciate his help.

Bosko should write a book called "pre-calculus" for dummies. It would be a best seller.

He is extremely patient and has a step-by-step methodology, which is leading to me understanding difficult concepts. I highly recommend Bosko for your math needs :).

In this (my only) instance he helped me online with a problem I was stuck on. He helped me learn how to dissect a problem and discover what the real question is. Helpful!

He helped me with understanding trigonometric functions, graphing said functions, going over the multiple rules and laws of sine and cosine, not to mention much more.

He takes each lesson seriously, and he is very patient. My daughter likes his way of teaching. Great tutor!

Bosko was very thorough in explaining Calculus equations with my son. He did a great review and provided him with a lot of feedback. Highly recommend.

Bosko is a very patient man. He will show you several different examples of how to do a certain equation or other problem. He always makes sure you understand everything before moving on to a different problem. I highly recemend him for a tutor

Bosko has done a great job getting our 12 year old son better prepared for his algebra tests. He helps him to not just learn the material, but know it inside and out.

Bosko has helped me with trigonometry greatly. He brings new lesson plans every meeting and notes that are specific to me. I enjoy learning with Bosko and will continue to use him as a tutor.

Bosko is a very good tutor; he takes the time to teach the material step-by-step and is good at clarifying any lingering questions.

Approved subjects are in **bold**.

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.

ACT Math can be very challenging for every high school graduate student because besides knowledge and understanding of math principles, it includes numerous things such as reading every question carefully and pacing.

So, the main goal is to give the correct answer in a short period of time (usually less than 60 seconds per question).

ACT Math consists mostly of Pre-algebra and Plane Geometry questions. Example for these questions could be from Analytical Geometry: distance between two points (x1,y1) and (x2,y2) on the graph: D=sqrt((x1-x2)^2+(y1-y2)^2), midpoint formula: ((x1+x2)/2, (y1,y2)/2), line through those points: y-y1=(y2-y1)/(x2-x1)*x-x1. Plane Geometry examples: area and perimeter of equilateral triangle: A=a^2*sqrt(3)/4, P=3*a; area and circumference of circle: r^2*Pi, S=2*r*Pi.

One of the core Algebra 1 problems is solving system of 2 linear equations with 2 unknown variables.

Factoring is such an important process of Algebra 2:

Here is an example that includes factoring and quadratic equation:

Find all solutions for: x^2-x-6=0.

We can use quadratic formula: x1/2=(-b+/-sqrt(b^2-4*a*c))/2*a, but there is more elegant way to get to the solution of this problem. Factor the expression: x^2-x-6. -6 can be considered as a product of 2 and -3 and gives us conclusion that -x can be written as a sum of -3x and 2x. So, our expression has this form now: x^2-3x+2x-3*2=x*(x-3)+2*(x-3)=(x+2)*(x-3). So, our quadratic equation looks like this: (x+2)*(x-3)=0. This will be equal to zero only if: x+2=0 or x-3=0. That means that solutions for this quadratic equations are x1=-2 and x2=3.

Fundamental tools of calculus are derivatives, integrals and limiting values.

Derivative is defined as limiting value of the ratio of the change in function to the corresponding change in its independent variable. Integral is defined as reverse function of derivative. Exponential Function e^x is very interesting since (e^x)'=e^x and int(e^x)=e^x as well.

I had a two semester class in Ordinary Differential Equations during my Financial Mathematics studies and I earned high grade. 9/10.

I also had a chance to deal with differentials during my Calculus 2 classes. I earned the highest grade in this subject, 10/10.

So, I think those subjects gave me an excellent knowledge and ability to teach all types of Differential Equations.

My educational background in Math & Engineering has given me an exceptional understanding of Discrete Math. I have taken a two-semester class in Discrete Math.

Also, my 7 year experience as a tutor provided me an opportunity to deliver Discrete Math knowledge in developing way to students' interests. I make learning process and understanding Discrete Math easier for students by initiating an interactive approach during my tutoring sessions and always keep improving their knowledge by giving them challenging problems in order to expand their potentials.

Example that represents volume of geometric bodies:

Sphere is inscribed in Cube. Cube has volume of 64 cm^3. Find the volume of sphere.

Cube's volume is defined as V1=a^3, where a is the edge of the cube. So, in this case: a^3=64; a=4 cm. Since sphere is inscribed in cube, that means that diameter of the sphere is equal to edge of the cube, D=2*r=a. So, radius of the sphere is r=a/2=4/2; r=2. Volume of the sphere is defined as V2=4/3*r^3*Pi=4/3*2^3*Pi=4/3*8*Pi; V2=32/3*Pi.

Bosko scored 95th percentile on his GMAT Quantitative.

Bosko had 95th percentile on his GRE score.

My educational background in Math & Engineering has given me an exceptional understanding of MATLAB. I was taking two-semester class in MATLAB and its applications in Algebra and Calculus.

I am specialized in route planning algorithms which was the main subject of both my master's

and bachelor's thesis (programmed in MATLAB), skilled in optimization of Markowitz portfolio with minimum risk method (programmed in MATLAB), deflation models (programmed in MATLAB).

Numerical skills are the core of Pre-algebra problems. Basic arithmetic operations with fractions are good examples:

1/2+((2/3)/(3/4))-(4/5*5/6)=1/2+(2/3*4/3)-(4/5*5/6)=1/2+(2*4)/(3*3)-(4*5)/5*6)=1/2+8/9-20/30=1/2+8/9-2/3 Now, we have to find LCD (Least Common Denominator) for these three fractions which is 18. So: 9/18+16/18-12/18=(9+16-12)/18=13/18

In Precalculus, analyzing the function usually begins with defining Domain and Range of the function: y=f(x).

Domain is subset of x-axis that corresponds to all possible values for x and Range is subset of y-axis that corresponds to all values for f(x) in the function y=f(x).

Here is an example: y=(2x+1)/(x-1). If x-1=0 then x=1 and f(x)=3/0. This value is not defined in set of real numbers, R. So, x cannot be 1 and our domain for this function is R/{1}.

When we solve y=(2x+1)/(x-1) for x: x=(y+1)/(y-2). If y-2=0 then y=2 and x=3/0. This value is not defined on set of real numbers, R. So, y cannot be 2 and our range for this function is R/{2}.

Example for Probability of Events:

Q: What is the probability of drawing 2 red cards (one after another) out of regular 52-card deck?

A: In regular 52-card deck there are 26 black cards (clubs and spades) and 26 red cards (hearts and diamonds). So, probability of drawing first red card is P1=26/52=1/2. Now, we have to draw second red card, but this time we have 25 red cards left inside the 51-card deck. So, probability of drawing second red card is P2=25/51. Finally, probability of whole event of drawing two red cards (one after another) out of regular 52-crd deck is P=P1*P2=1/2*25/51=(1*25)/(2*51); P=25/102.

Since trigonometry has wide application in Engineering and Science, I was taking trigonometry classes throughout all my high school and college education and I was always the best in my class.
