I can't agree with you. In my opinion, each test corresponds to the curriculum and contains questions on the most important knowledge in the subject or profession, necessary for the student to become a specialist (or just more aware of it). If we are talking specifically about the CSCS personal trainer certification exam, then you can get an idea about the upcoming test on special resources, for example, here <a href="https://traineracademy.org/training/cscs-practice-test/">https://traineracademy.org/training/cscs-practice-test/</a>; I found a complete description of this test, an approximate preparation plan for it, the necessary materials and even a checklist that will allow you to accurately don't forget anything important. In the online Trainer Academy, you can get and use such studying guides (as well as textbooks, reminder cards, etc.) for free. It really helped me a lot as I prepared for the Strength and Conditioning Specialist Certification.
