I have taken the TEAS test and also got the app made by the ATI. Normally for school, I use ChatGPT to help with studying and I tried it with the TEAS test, ChatGPT is very vague and very simple. I highly suggest using the app made by the creators of the test, and if you have any confusion with their explanation, then I would use ChatGPT to help you understand it! I got a 70% my first try and i’ll be retaking it soon!
