ILIA KOLMAGOROV. HE IS THE BEST!!!!! HES SO FUNNY AND CHARMING THAT YOU CANT HELP BUT WANT TO LEARN. He is such a good teacher. Very calm and patient, yet hilarious. I loved the 8 week class so much that I already recommended prep expert to a friend!! He is actually the best teacher I've ever had. This might have been the most enjoyable class I've ever been in, not going to lie. GET THIS MAN A RAISE. Ilia is such an absolute wonderful person to spend 6 hours of my weekend with. I really enjoyed this. This 8 week class has been long but it was so enjoyable because of Ilia. My score improved around 300 points!!! I give all the credit to my teacher, Ilia Kolmagorov. He is very patient and understanding when students are confused and it is very reassuring. Prep Expert inspired me to be the best version of myself. I WILL DEFINITELY BE BACK FOR MORE!!!!!!!! This review is truly coming from my heart. Thank you.
