Get yourself Fitzpatrick. They have some good questions in there.
What you want mostly for maths anyway is lots and lots of questions, the more questions you do - the better you'll be at maths.
Well if there are '10 easy marks' in MC, why don't they compensate by making more difficult questions in Q11-16?
Plus, ME1 had 84 marks - and they had no problems with cutoffs.
Just do the best you can!
