How a diagnostic works

  1. 1Answer the questions against the clock. The timer matches the pace of the real exam. You can skip and come back, and the progress grid shows what is still open.
  2. 2Get a score by area. The report shows your overall result, then each exam area with its weight on the real exam and how you did there.
  3. 3See what to study first. Areas where you missed the most questions and that carry the most weight are ranked at the top of the report.
  4. 4Read a worked solution for every question. Each one walks through the answer step by step and explains why the other choices fall short.

How the questions were checked

The questions come from the free sample of each PassExams question bank. Before a diagnostic goes live, every answer key is worked by hand twice, independently of the bank, and an independent AI review then re-solves every question from the stem alone. Items with two defensible answers are dropped or reworded until one answer stands.

Each diagnostic also states its time limit and area weights on its own page, with the source of those weights. The FE Civil set follows the NCEES FE Civil specification, the NCLEX-RN set the NCSBN test plan, and the USMLE Step 1 set the official content outline.


Questions

Are the diagnostic exams really free?

Yes. Each diagnostic is a public page with no sign-up and no payment. Your answers stay in your own browser.

How long does a diagnostic take?

Most have 40 questions. FE Mechanical has 39, USMLE Step 2 CK has 37, Bar MBE has 21 and LEED Green Associate has 16. FE Civil allows 120 minutes, FE Mechanical 117 minutes, NCLEX-RN 80 minutes, USMLE Step 1 60 minutes, Step 2 CK 56 minutes, Bar MBE 38 minutes, PMP 53 minutes and LEED Green Associate 19 minutes, which matches the pace of the real exam.

What do I get at the end?

You get a score, a breakdown by exam area, the topics to study first and a worked solution for every question. You can also save the report as an image.

How were the answer keys checked?

Every key was worked by hand twice, independently of the question bank, and then checked once more by a separate AI review before the page went live.

Can I retake a diagnostic?

Yes. The report view has a reset that clears your saved answers and starts the same questions again with a fresh timer.
