Hi , me and my friend are in the exam same boat as you i didnt get great this results day so decided i to resit. But no colleges will accept a student like me due to the changes in specification. They said that theonly thing we can do is sit the exams as an external student, so it looks like i will have to learn everything again at home by myself with out a teacher. dont know how I am going to cope tbh. Also you can resit AS exams so that calmed me down a lot.
