We trust that you will not share our products with your friends, relatives, or even siblings. In return, we offer you our support and the lowest price out there. MCAT Self Prep is a family business, which provides a livelihood for those working hard to provide you with quality test prep. By offering students lifetime access to our pro plans, we run the risk that you will share your account with others, ruining our ability to stay in business. Instead of having expiration dates for plans or implementing strict security protocols, we believe in having a relationship of trust with you. Please treat us with kindness and respect in return.
