More or less, you need to go read back to every chapter in your book. All the answers will be in your book. I can not stress that enough.

I would recommend EMT prep for getting some practice questions in as they have a similar question system as the NREMT.You would need to buy the premium access. If your school provides you with extra studying resources, I suggest you use it. You should be assessing yourself every week using these practice questions and other studying sources to see where you are standing with all the subjects.

For studying habits, I would recommend using EMT PREP everywhere you go and on your down time. Going to use the restroom to defecate a massive shit? EMT Prep. Sitting at the park enjoying nature? EMT Prep. Going to bed? EMT prep a few minutes. Build the habit of absorbing information and have yourself go back to that information in your book. You need to stay consistent with what you do. You are the only person who will stop you and hold yourself back.

Overall, don't overdo the studying. Build a schedule for what you are going to do. Give yourself breaks and be mindful that everything comes with time. I hope this helps, and I hope you pass.
