What are your feelings on the eve of an important examination? Do you feel any sort of anxiety even after a good preparation? If so, why?

Explanation

On the eve of an important examination, I feel nervous and stressed because the exam is going to happen the next day and all the preparations and study of so many months will be tested finally. Yes, I get a little anxious even after I’m all prepared because there are some thoughts going on in mind naturally, what type of questions will come, would I be able to answer them properly, have I prepared enough, etc.
