Levels Taught:
High School, College
Sometimes calculus looks scary. It usually happens when things that we are doing are too abstract for us. I help by connecting calculus to real life and helping my students to understand why we are solving this problem this way and probably invent their own way to solve problems. It's not only helping to improve the grades but also helps with confidence.

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.

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.
