About Bosko

I work as a Teaching Associate on various Math subjects on California State University San Marcos and I have Master's in Industrial Engineering and Bachelor's with Honors in Financial Mathematics, so my educational background gave me exceptional understanding of Mathematics and its applications in real life. Also, my 12-year experience as a teacher and tutor provided me an opportunity to deliver math knowledge in developing way to students' interests in math as a science.

I make learning process and understanding math much easier for students by initiating an interactive approach during my tutoring sessions and always keep improving their knowledge by giving them challenging math and logic problems in order to expand their potentials.

After each session, I always give them homework, printed material and written notes (in 5 colors of ink) with all problems we went through together. This is how I make easier for them to visualize and absorb information explained during the session.

Students can expect my help in wide spectrum of different math fields such as: Algebra, Calculus, Geometry, Trigonometry and Probability; including various areas of Applied Math as well. I also prepare students and improve their performance in SAT Math, ACT Math, GRE and GMAT.

I am probably not kind of low-price tutor, but I have a lot of self-esteem in my knowledge and tutoring strengths.

I always keep myself at high standards and always look for a feedback from my students. I usually tutor at their home, but I am also happy to travel to other locations, wherever is more convenient for my students.

My schedule is very flexible.

I am looking forward to hearing from you and help you achieve your academic goals.
So, Let's win together!

Approved subjects are in bold.

Approved subjects

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

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.

Algebra 1

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

Algebra 2

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.

Calculus

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.

Differential Equations

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.

Discrete Math

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.

Geometry

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.

GMAT

Bosko scored 95th percentile on his GMAT Quantitative.

GRE

Bosko had 95th percentile on his GRE score.

MATLAB

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).

Prealgebra

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

Precalculus

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}.

Probability

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.

Trigonometry

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.

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
