text: do mock gcse exams actually matter? i've gone from sleep losingly worried, to not caring anymore about my gcse mock exams i've got in three weeks. they're not my actual exams and they don't actually count but everyone else is getting worried. my r.e teacher told me and my friend personally not to worry but should i? your re teacher may not worry, but what about the other teachers? my son sat his a year ago, he did so bad in one subject, they moved him down 2 sets fearing he would not be able to cope with the gcse........bear this in mind and get your books out!
