HESI A2 Chemistry Practice Test With Answers

Focus on atoms and ions, bonding basics, periodic table patterns, reaction types, solutions, and acids and bases.

No. You need to understand the structure, common trends, and how to use the table to compare elements.

Usually concept-heavy with light calculations. Clean fundamentals and careful reading matter more than complex math.

Track units, write the relationship you are using, and double-check decimals before you choose an answer.

Know pH basics, strong vs weak, and what happens when acids and bases react. Then practice a small set until the pattern feels automatic.

Choose the option that matches the definition or rule being tested the best. Wrong choices often sound close but ignore one key detail.

Yes. Retake it after a short gap to confirm you learned the concept rather than memorizing the answers.

Stop and drill that topic alone for 15 to 20 minutes, then retest. Most chemistry improvement comes from fixing repeat patterns.

At this level, you should understand what balancing means and be comfortable with simple examples, but the focus is usually on core concepts and basic relationships, not long, messy equations.

Track electrons in plain language: oxidation loses electrons, reduction gains electrons. If that feels confusing, use the quick memory trick “OIL RIG” and practice a few items until it clicks.

They can appear, but usually in a light form. Expect simple mole or ratio logic rather than multi-step problems.

Know the basic idea of how pressure, volume, and temperature relate. If you can explain the direction of change, you’re already ahead.
