Learnerator | About Us

Upgrade

We started Learnerator to be the best resource for AP exam prep available on the belief that taking practice questions is the most effective way to review and prepare for the AP exams

	Luke Liu Founder, CEO When Luke was in high school, he took 11 AP courses and scored 5's on all except one (too embarrassed to say) and thus has experienced plenty of the pain involved with preparing for AP exams. He even taught himself AP World History when his school didn't offer it, reasoning that since he had already taken AP European and US History, that adding the rest of the world would not be so difficult. Luke graduated from Northwestern University with a B.A. in Economics. If you have any questions: luke@learnerator.com @LukeTLiu

	Sussy Shi COO Sussy graduated from her high school, The Charter School of Wilmington, with 9 APs under her belt. Her favorite AP in high school was AP Microeconomics. She doesn't usually regret her decisions, but if she had a chance to retake an AP exam today, it would probably be AP Chem, and she would do so with the help of Learnerator! After high school, Sussy decided to pursue a bachelors degree in her favorite AP subject - Economics. AP courses proved to be useful as she was able to graduate from the University of Pennsylvania with a double major in Economics and Communication. If you have any questions: sussy@learnerator.com
