The free HESI A2 Science Survival Kit.

Anatomy, biology, chemistry and the math the A2 actually tests, mapped visually across a few pages so it sticks. No 400-page textbook, just the parts that score points.

Heart and blood flow, gas exchange, the cell, atoms and pH, and the conversions you can't dodge. Built the same way nursing students use to make pharmacology hold still.

Chemistry sheet from the kit: a labeled carbon atom diagram, a table of protons, neutrons and electrons, and the pH scale explained.
The Heart sheet from the kit: a labeled four-chamber diagram, blood flow in order, the four valves, and the numbers to know.

What's inside

Five sheets. The science the A2 leans on.

Each one is a single visual page: the diagram, the rule, and the trap the exam likes to set. Read it once, recall it under pressure.

  • The HeartFour chambers, the valve order, and blood flow direction.
  • The Respiratory SystemAirway path and how gas exchange actually works.
  • The CellOrganelles, division, and what each part does.
  • Chemistry EssentialsAtoms, bonds, and reading the pH scale.
  • The Math You Can't AvoidThe formulas and conversions the A2 expects cold.

7-page PDF. Reads on phone, tablet or print. Yours free, no purchase needed.
