If the 9 exams have to be done in the same day and it's your biggest concern don't worry so much for it, in Hungary is the same and didn't feel like an impossible task, read the theory and put 100h of QB studying the 14-10 days before and should be fine, I started at 9am and walked out after completing the 9 exams around 12.15 just having 2-3 very short breaks to visit the bathroom and eat a chocolate bar. Perfectly doable.
You will find exams where you get 30' to complete it but 18/20 of the questions are from the bank and you will be done in 5 mins anyway, is quicker than planned.
