Our story
maxacer started with a simple belief: getting into college shouldn't depend on your zip code or your family's income. Too many capable students are held back by the cost of test prep — expensive tutors, paywalled materials, and limited guidance.
College entrance exams open doors to scholarships and admissions. We built maxacer as a non-profit to make world-class exam preparation free for every student — because opportunity should be earned through effort, not bought.
