PrepScholar

PrepScholar uses machine learning to watch what you get wrong and serve more questions like it, personalizing every student's path through the curriculum. If you're weak on reading comprehension but strong on math, the platform tilts your practice heavily toward reading. This personalization cuts study time because you're not grinding concepts you already know.

The service covers the SAT and ACT for high school students and the GRE for graduate school applicants. Each comes with video lessons and a full question bank. The adaptive approach appeals to students who want to maximize their score without wasting months of generic prep schedules.
