Online Study Library for Students
Join quiet online study rooms, plan focused study sessions, and track camera-verified focus time with PrepLib.
Study alongside others
Choose the main study hall for drop-in co-study. Bring a task you can finish in one sitting, such as reviewing a chapter or solving five problems. Free accounts can preview the live main hall once for 2 minutes and 30 seconds.
Build a repeatable routine
Reserve a study block in your planner and enter the hall when it starts. Review room time and verified focus in Study History to see how consistently you followed your plan.
Understand verified focus
The timer credits eligible time while the camera detects face presence and the room connection is active. Use your notes or practice results to measure what you learned.
