"was def behind on studying and almost didnt sit for it. the practice questions on electronic engine controls saved me, thats 40% of the test anyway. missed passing by a hair on my first mock then just kept redoing the ones i got wrong until it clicked."

"did the mock exams a few times before my actual test date. air induction stuff was always my weak spot and seeing it broken out seperately helped me know where to focus instead of just guessing. passed first try, no drama."
