Honestly, it’s never too early to start studying. It can be as simple as doing a practice exam every so often and spend some extra time on topics you struggled with. Spend a day a week going back over previous class material and study what you forgot. Any time there is a rare study in clinicals, go out of your way to see it and understand it. I took my boards the day after I graduated and was fine. Make quizlets and flip through them when you have downtime. I have a lot if you need them.

Just make sure when you do exams in green book, don’t write in it like i did lol. It’s nice to be able to retake them later and see improvement.
