When you are preparing for the scientific portion of the HESI A2 exam, it may appear to be a mountain, but with the right resources and approach, you can confidently climb it. The Rhenis Review Nursing Q-bank can help you master the HESI A2 science section with focused practice and high-yield review. Everything you need to know about it is provided in this guide.

What’s on the HESI A2 Science Section?

The HESI A2 science section typically includes:

- Biology

- Chemistry

- Anatomy & Physiology

- (Sometimes) Physics depending on your school’s requirements

Your fundamental understanding of scientific principles, which is necessary for success in nursing school, is put to the test in each subsection. Everything from cell structure and DNA replication to chemical equations and body systems will be required of you.

 - The structure and function of cells 

- The meiosis and mitosis 

- The production of proteins, DNA, and RNA

- Genetics and inheritance

- Macromolecules (proteins, lipids, carbohydrates, nucleic acids)

- The process of photosynthesis and cell respiration

 ~ Tip: Focus on vocabulary and processes. Using flashcards and diagrams reinforces biological pathways. Chemistry HESI A2 ~

 - The periodic table and atomic structure 

- Chemical interactions and bonds 

- pH, bases, and acids 

- Mixtures and solutions 

- Metric conversions and dimensional analysis

- Fundamental organic chemistry

Advice: Practice balancing equations and commit important formulas to memory. For recurring trends, use mnemonics.

Anatomy and Physiology: The main bodily systems (digestive, respiratory, cardiovascular, etc.)

Homeostasis and feedback systems; tissue structure and cell kinds; hormones and endocrine regulation

~ Tip: To make the connection between anatomy and physiology, use idea maps. Get comfortable labeling diagrams. ~

Practice exams help you by simulating the actual exam.

Determine your weak points.

Develop your test-taking endurance

Enhance time management; repeat information to reinforce it.
