AEP practice questions - frequently asked questions

Plain answers about how AEP 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 AEP exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The AEP exam spans 5 domains: Environmental Laws and Regulations (44% of the exam); Environmental Program Management (24% of the exam); Basic Chemistry, Toxicology, Geology/Hydrogeology (22% of the exam); Environmental Technology (7% of the exam); Environmental Ethics, Legal Obligations and Personal Liability (3% 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: Environmental Laws and Regulations 44%; Environmental Program Management 24%; Basic Chemistry, Toxicology, Geology/Hydrogeology 22%; Environmental Technology 7%; Environmental Ethics, Legal Obligations and Personal Liability 3%.

The AEP exam has 100 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
