PrepExpert is a scam. The online teacher was monotone and not engaging with the students. He read from a book and seemed socially awkward on camera so much so that it made my daughter uncomfortable and not trustworthy that he knew what he was doing or talking about. My daughter didnt have any improvement on the ACT after the 6 week course, including all of the homework and tests that came with it. And their refund policy is a joke. Their "Senior Director of Customer Experience" , Ryan Quadro, talked down to me on the phone and seemed like he was reading from a script. Very impersonal and not who I would recommend to be the "Senior Director" of Customer Experience. This is a money hungry company and they dont care about the students. I highly recommend Princeton Review. My daughter did significantly better on her ACT after a 2 week online bootcamp. The instructor was engaging and made one-on-one time with each student. Princeton Review actually cares about the students and how they do. PREPEXPERT ONLY CARES ABOUT TAKING YOUR MONEY.
