Congratulations on pursuing CAP! The practice exam is a tool. Use it to gain experience, understand the format of the exam, etc. It is largely made up of questions from previous exams that have been retired. Your will get your results presented in a similar way as the real exam. You won't know which questions you got right and which were incorrect. If you can take the practice exam and use it as a tool, a measure of which domains you are stronger in and which ones you are weaker, to focus your study, then 100% take the exam. If a poor outcome on the practice exam will discourage you, I would not take it. I took the practice, I want to feel what the experience would be like. I was able to refocus my studies to areas that need more concentration. I also highly suggest a joining a study group. The study groups for the fall exam session will be announced later this summer. Good luck! Please do reach out if you have any questions.
