Notes From Students & Teachers

See what past students and teachers are saying.

"I failed my class final for AP Human Geo and realized I had to really study if I wanted to pass the AP exam. I found and purchased the URP, then studied my butt off the last two weeks leading up to the exam. My teacher thought I would fail, and I got a 4. The URP is the greatest thing ever created."
Jude S.AP Human Geography · Scored 4
"I taught AP Psych for the first time with very little support from my school, so I bought the URP for all my students. Ten of them scored a 5, and five scored a 4."
KathleenAP Psychology teacher
"The packet is the holy grail if you want to score well on the AP Psychology exam. The videos and quizzes are a lifesaver."
Cadan F.AP Psychology · Scored 5
