To help you reach your personal academic goals, (whether it be pre-Algebra, Algebra, Geometry, Trig, pre-Calculus or Calculus, SAT, and/or the ACT test preparation, or may be GRE preparation for an older audience) I will find your weak topics and help you understand it fully. For that, I analyze your previous work and we discuss what you did and why. I will help you to see the logic in the solution and understand the relationship between concepts. Between sessions, I will happily answer short questions off the clock by email, or Skype.

For the SAT/ACT test takers my plan is usually for a student to take the practice test at home or school, then grade it and come back to me with the results. We will diagnose your problems (as in “didn’t have enough time”, “don’t know how to approach a problem like this”, “didn’t read the problem carefully”, “made a calculation error”, “didn’t know the definition” and so on) and work specifically on that. I always customize my lesson programs in accordance with student's' need, for example, I can give you practice problems that you can work on in between lessons and it will help you to solidify your understanding.

I create a very comfortable learning environment, you will enjoy your intellectual achievements during our sessions.

I worked successfully with students of all levels, including those who were struggling with elementary level math, those who needed more help with the GT program, participated at Math Olympics, or struggle with the high school or college classes. My students’ grades and self-confidence showed improvement even after the first class.

I have many years of experience teaching mathematics, in several countries and to different people. I worked as a university instructor, volunteered with struggling kids at local schools, tutored for test preparation, and led activities at a summer camp for gifted children. I also worked a lot with homeschooling community. I worked successfully online and offline, in a group setting and one on one.

I have a master's degree in Mathematics from Cleveland State University and could help with a deep understanding of my subjects well behind the school level. It will help you later in your study and work. My students not only improve the grades and move up in a class rank but also like math much more after working with me. Some of them actually stopped being afraid of math and started to enjoy it!

I am flexible with time. I do have the 24-hour cancellation policy and also my students have an opportunity to reschedule the class they cannot attend. It is important to me that my students have a choice to work with me online, so there are fewer chances of weather-connected emergencies in our work together.

Marina was very effective in helping my daughter with geometry. Marina was patient and worked with her step by step. My daughter felt a little more confident with geometry after her first lesson.

We are very thankful to our instructor. She makes sure the subject is understood and not memorized. One could see that she has passion for the class and it looks like that passion is contagious.

What a life saver! My son was having a hard time with Calculus. Even if I could help him, the stress level would be unbearable.

Marina was able to answer specific questions, was very flexible with my son's s schedule, very patient and knowledgeable on the subject matter. His grades went from near failing to a B....

We took lessons from Marina through skype for our two children. The focus was on developing more fluent reading and writing skills. Marina offered a variety of frequently changing activities to keep my children engaged throughout each lesson and the course of the study.
