3rd Week into the EDLD 5344 Class

I know I over-analyze everything but taking the mid-term for the EDLD 5344 class (Business Law) proved that.  I'm thorough in my notes and still wondered if my answers were the correctly ones.  I wonder if over-analyzing is a good thing or a waste of time?  Do I put more pressure on myself by over-analyzing or is being thorough a good thing?
