my son is coming to the end of his first year studying bio medical sciences. although he has coped ok with the course (after an awful lot of commitment and hard work) he is really panicking about his upcoming exams and is worried sick. I have no doubt on his efforts but he seems to think whatever he is revising is not 'sticking' and he's really concerned he'll fail his first year exams. does anyone have any suggestions on revision techniques or how he can calm himself down? I feel helpless!
