I was excited to find Eric on Grockit because I needed someone who could help me with a daunting task: SAT Math. Even though I have a long way to go, Eric helped me so much and I am positive that when it comes to test day I will appreciate every bit that he made easier for me. He doesn't put people under pressure either, and he's always explaining some difficult points that I have trouble with, but while still having some fun. Thanks so much, Eric!
