I would advise u not too get stressed about it first of all...
Sure at the end of the day they are only exams and u sure u can resit them.
Things aren't always as bad they seem.
In my opinion, the key to these exams is practice, practice, practice.
Go over and over the feedback, but make sure u don't spend loads of time on a question that is one mark as opposed to one that is two/three.
At one stage, during the two week brush-up course, I felt very overwhelmed but you got to get a clear plan in ur head, don't think of all the work u have to get done, otherwise it will melt ur head....You got to break it down and do it bit by bit....
You will be OK, trust me, we've all been there
