ABC-BIO practice questions - frequently asked questions

Plain answers about how ABC-BIO Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real ABC-BIO exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The ABC-BIO exam spans 8 domains: Science and Math (27% of the exam); Process (23% of the exam); Laboratory (13% of the exam); Computer (10% of the exam); Quality Assurance/Quality Control (9% of the exam); Communication (8% of the exam); Forensic Disciplines (6% of the exam); Legal (4% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Science and Math 27%; Process 23%; Laboratory 13%; Computer 10%; Quality Assurance/Quality Control 9%; Communication 8%; Forensic Disciplines 6%; Legal 4%.

The ABC-BIO exam has 60 questions and is completed in 1 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
