^That's what happened to me. And this was in the first week of exams, so I didn't have as much time as you to prepare.
Having a break leads you towards holiday mode, then its hard to come back out of it. We all say if we had the extra week we would have stuided, but would we have really? 
Yes i've been studying everday and I had a 10 day break between exams lol
I've been studying everyday since the end of semester, so thats 18 days up until the first exam,.....and now feeling the effects of it. And still not ready for electrical....... it just doesn't seem to stick to the laws of physics, I put work/energy in, but it gets lost, it doesn't come out the other end for electrical for me!

EDIT: It would help if I did spell electrical right.....
