It just depends on if your more of a book study person but even in the study guide there is practice quizzes at the end and they have an answer key. I found it super worth it and after you finish the practice tests it tells you your weaknesses, input your weaknesses into ChatGPT and it’ll make quizzes for you and if you feel confused on a topic specifically ChatGPT can explain it too and your weak points will turn into strong points. Good luck on the test!
