Practice Questions and Data Sets
Work timed sets of original CLEP Biology questions that use experimental tables, pedigrees, and cladograms, and review misses against the three College Board content areas.
Can You Take the CLEP Biology Exam?
Check if you meet the basic eligibility requirements
- •Register and pay in the My CLEP portal, then schedule separately with a test center or remote proctor
- •A parent or guardian consent form is required before College Board creates an account for a test taker under 13

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
