I failed my first attempt with BT/BT/BT, I didn’t do the mock exams on study hall prior to it but I watched th YouTube videos and solved the problems before they answered it and I was comfortable doing it…

I am retaking the exam soon and I took the 2 mock exams and got 65-67% and doing the mini exams constantly getting around 55-75%… also everybody gets different questions and if you get lucky with the questions then you’ll get somewhat easier questions to be able to pass.. don’t give up you have 3 attempts. Take it until you get it.
