What They Have to Say

“You may not remember me, but I took your GRE class at CSUN a few months ago. I wanted to write to say a few things. First, as you know I hate math. Second, I’d like to thank you SO much for all the skills you taught our class. Not only did I have a blast learning with you but I really learned a lot!

I took the test last night and did really well :) I scored above what I wanted and what I thought I’d be able to. I’m going to take it again in a month in hopes to do even better. The anxiety I had before taking your class was all but gone.

So, thank you Avi! You are a wonderful teacher and an incredible motivator!”
