Credit Sprint's Guide to the CLEP® Biology Exam

The exam at a glance

  • About 115 multiple-choice questions in 90 minutes. Some are unscored pretest questions, so don't panic over a strange one.
  • Scores run from 20 to 80. The American Council on Education recommends credit for a 50, worth 6 semester hours, but each college sets its own score and credit amount.
  • The content splits evenly: molecular and cellular biology (33%), organismal biology (34%) and population biology (33%).

Before you register

  • Check your college's CLEP® policy first: the score it requires and the course it gives credit for. Search your registrar's site for "CLEP".
  • Finish the free Modern States Biology course to get a voucher that covers the exam fee.
  • Check whether a lab component is required separately. Some colleges give lecture credit only.

Test center or at home

  • Test centers are often on college campuses. Bring an approved photo ID.
  • At-home exams use remote proctoring with an equipment check, an ID scan and a room scan before you start.
  • Read the official at-home testing requirements well before exam day.

On exam day

  • Pace yourself: 90 minutes for about 115 questions is under 50 seconds each. Answer what you know, flag the rest and come back.
  • There's no penalty for guessing, so answer every question.
  • Your score appears on screen right after you finish (except for some exams with essays, which Biology doesn't have).

After the exam

  • Scores sent to colleges can take a couple of weeks to arrive, and the college may need more time to post credit.
  • If you don't pass, you must wait three months before retaking the same exam.
  • Use the wait: your mistakes notebook and a fresh study plan will be ready.
