What do my fluctuating exam result dreams mean? if anything...?

I’ve had several dreams about my exam result that is due in two weeks time.
The first dream I had I got 85% (I couldn’t believe it)
The second dream I had I got 70% (I was gutted)
The third dream I had I got 100% (and was obviously elated!!)
The fourth dream I had I got 64% (miserable)

The fact is that if I get 85% for my exam I will have passed the course with a distinction, anything over 40% and I pass anyway. I really want the distinction of course.

However, I wondered what these dreams collectively tell you about me and what you read into it if anything
