ATI TEAS Ultimate Study Guide

Understand the ATI TEAS Exam

Four parts:

  • Science

  • Math

  • English Language

  • Reading

What you need to study:

  • Study Guide you can get mine here

  • ATI TEAS online practice exam

  • Use youtube videos to learn certain concepts in the math, science, and english sections that you do not understand. I have an entire Science study series here

Science Section

The ATI TEAS Exam is testing you on "high school level" subject matter meaning you do not need to know advanced concepts. For example you do not need to know advanced pathophysiology related to anatomy and physiology but you do need to understand how the system works, how it is set up, and the main functions of different organ systems.

I have created a free Science study series. You can follow along with the ATI TEAS Science Study Guide or get the full study pack here
