My instructor was Suzu Paudel- she was great, her instructions and tips were very clear and she helped to simplify the skills and tips- she made it a lot easier to implement in my SAT taking. PrepExpert as a whole is wonderful- giving tests every week really helped bring up my score- almost 300 points! The skills that they taught were like no other SAT resource, and I found that it truly changed the way I took the test. Highly recommend!
