General Biology Practice Exams

Chapter-simulation practice for a college General Biology course: 1,530 original questions across 21 chapter groups. Start with the free 12-question sample, sit full 100-question simulations drawn fresh across every chapter group, and drill one chapter group at a time (10 questions per drill) to target the material your next unit test covers. Every question includes an explanation. Simulations are scored against a 70% practice benchmark — your instructor’s grading standard is the one that applies to your course. The program is $9, with 6 months of access.
