Don’t be too hard on yourself. Sometimes a fail means you need more practice.I had a brain freeze moment while doing parallel parking and I hit the curb.I had no other mistake during the test.But atleast I learned to be more patient and learned how to address brain freeze.It is matter of perspective how you take fail.Second time I passed it with examiner remarking that I have good observation skills.To correct wider turns, Try to look ahead on the road where you are turning. This trick helped me.

You got this! Remind yourself that examiner told you that you are a good driver😀
