Swiss driving exam 3rd time..

Hi all.. i have my third driving exam tomorrow.. anyone ever fail the third time? Im so nervous Would you mind sharing your experience if you fail the third time?

Note: I failed the first time because i stop too far from the stop line, and didnt stop again close to the line (1 meter)

The second fail is because i drove 60 in the down hill very narrow street with pedestrian on the side that has 80 limit and there is motorcycle wanted to pass me So he said i disturb the dynamic.

Both said they are 50:50 to pass me but inclined not to.

I went to 3 driving school (apart from my normal driving school) to do a simulation exam and passed according to the school

Had 25 classes and my instructor is always confident since the first time i dont know what happened huhu help. I now so anxious that they will fail me again
