I applied last year and the paper was not to bad, i then had my interviews and a few day later i got a leter in the post saying i have been given a condictional offer (AAA), unfortunitly, i never met the condiction grades due to some problems at home and college.
I went to a normal school and a fe college, I had obtained A*AABBBCCDE in GCSEs and in my as levels AAAC.
So getting good grades is not nesseserilly the case, It also depends on what chances you have had to get the grades.
I applied for St Johns and most lads their went to fee paying schools, and had all A*s with a few As in GCSEs and AAAAA at AS level and most got rejected, because those grades are expected in there schools, the people that seem to get in most where students obtaining better then their schools expectations.
One lad who had been rejected last year is applying again this year after getting AAAA in Alevel. He wants to study mathematics and his grades included Maths, furthur maths and english.
I also found that their is not much point applying if you not getting the A2 in furthur mathematics.
