From the parent: * After completing the course, my daughter did not achieve the guaranteed result. Because she had a 1320 on her previous SAT, Prep Expert "guaranteed" a 150 pt increase and she achieved an 80 pt increase. * Prep Expert declined to honor the guarantee and refund the price I paid for two reasons: 1) ONE of the essay's as part of ONE of the SIX practice tests was late (note that essays DO NOT count toward you SAT score) and 2) she missed answering the tutoring session poll questions by 1% (79% vs required 80%) * I wrote to Prep Expert customer service explaining the neither of their reasons for not honoring their guarantee impacted my daughter's actual SAT score but they are very rigid and lack a customer-first mindset. For the above reasons, I would not recommend Prep Expert. From the student: * Too much of the online tutoring sessions were spent reviewing questions she did not miss. * Customer service was slow.
