Is fear of failing exams the biggest mental challenges that student face?

[Henrywrites]

I highly doubt that there are any student that would wish to fail their exams. I mean, everyone wishes to pass their exams. However, I am beginning to think that the fear of failure might be causing a lot of mental stress on the students where they keep thinking how everyone will behave towards them if they discover that they failed at that time. Do you consider it a big challenge?
