You get all the info you need here

I passed the test two days ago with a score of 823 and I can say with certainty that you will learn what you need for the actual exam from these mock exams. I did the tests multiple times and took notes whenever I saw something in the explanation that was new to me, even if I answered that question correctly, there was always something to learn. Don’t be discouraged with your scores as these questions are good at pointing out any possible blind spots in your knowledge.
If you can get 90% in all of them there is no question you can’t answer.
Wishing you all the luck and a big thank you to the tutorial dojo team, especially Jon.
