So I failed my drivers test 2 times, switched driving schools and was doing better. A few days before my 3rd exam I made really weird and unexplainable mistakes. The last lesson before my test I almost drove myself into a heavy accident if my instructor didn't brake (car coming at the driver side with +-75km/h).

I told him that I felt like I get way too anxious/stressed when the exam comes closer and make weird mistakes. He told me to ask my doctor for something called Propranolol (a betablocker which lowers the heartrate). I took it and my test went very well!

Now I called to get more for when I have a big test or presentation and I'll get them tomorrow.
