I think every one goes thru the same feeling, making stupid mistakes, nothing going in, some things sound like a complete new subject that you have never seen before..
I remember around the same time before our exams, we were full time class, a few of us took a night away from books and went out on the lash in Bournemouth, the break did us the world of good...a good laugh a few beers and not a mention of anything ATPL related just beer, ladies and kebabs
