Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 400.

Science

Which organelle is known as the 'powerhouse of the cell'?

  1. ANucleus
  2. BGolgi apparatus
  3. CRibosome
  4. DMitochondrionCorrect

Why: The mitochondrion produces most of the cell's energy in the form of ATP through cellular respiration. This role earns it the nickname powerhouse of the cell.

Mathematics

What is 3/4 + 1/6?

  1. A7/12
  2. B11/12Correct
  3. C1/2
  4. D4/10

Why: Find a common denominator of 12: 3/4 = 9/12 and 1/6 = 2/12. Adding gives 9/12 + 2/12 = 11/12, which cannot be reduced.

Questions

Asked before starting.

Is the practice really free, or does it stop after a few questions?

All 400 questions, the timed mock and the report are free with no sign-up. A free account only adds saving your progress. The study guide book is sold separately, $29.99 one-time; nothing in the practice requires it.

Is your mock the same as the real HESI A2?

No. Ours is 100 questions in 120 minutes; the real exam is 120 questions. Use the mock for stamina and section timing, not as a score predictor.

Is there a study guide for the HESI A2?

Yes. PrepPass sells HESI A2 Exam — Complete Study Guide (2026), a PDF + EPUB download, $29.99 one-time; the practice on this page stays free without it. See the study guide →
