If you’re prepping for the HESI A2 entrance exam, you know the biology section can be a doozy. It’s one of the key components that many nursing and healthcare programs look at, so you can’t afford to mess it up. Let’s break down the HESI A2 biology section, including how many questions to expect and the best ways to tackle them.

What to Expect in the HESI A2 Biology Section

The HESI A2 biology section tests your knowledge across several core topics. Here’s a quick rundown of what you’re likely to see:

  • Cell Biology: Questions about cell structure, organelles, and the functions of cells. Think mitochondria, ribosomes, and the whole process of mitosis and meiosis.
  • Genetics: Expect questions on DNA, RNA, transcription, translation, and basic heredity principles. Punnett squares are fair game, so be ready.
  • Evolution and Ecology: You’ll encounter questions about natural selection, adaptation, and ecosystems. Food chains, energy flow, and population dynamics could pop up too.
  • Human Biology: A good chunk of the questions will focus on human anatomy and physiology. This could include anything from how the circulatory system works to the basics of human digestion.
