Knowing Your going to Fail in your GCCE's

Does any 1 else know there going to fail there GCSE's?
Well, Im in middle set, and I used to get B's + C's. And I liked all the people in the class. I could work well, as you can trust others in the same class you have been in for 3 yrs.
But now, Iv been moved up into Band A classes, and theres no one from my class, except a few (But there ppl I don't like) and I just don't feel comfotable. I can't concentrate on work, knowing some 1 will abuse me in some way.
And in English, Our teacher had to go for serguery, and our suply teacher is ****. And not only that, my folder with ALL of my complete corsework got:
Tipex all over it, spat in it and then went missing from the classroom (Probably got burnt).
I have posted a thread about my maths teacher.
The only 2 lessons I will probably pass in are:
BTEC Science (The teachers r good, and actualy help u)
and I.C.T. as Im ahead of every 1 in this lesson xD

Is any one else in the same possision?
Just because the school didn't let me move into the other class in the first place.

Also, is there another corse I can do when we finish, where I can re take English and Maths?
