it was my first day of yr12 yesterday, and when i received my timetable one of the options was wrong- i was put into psychology instead of chemistry. although this makes sense, because pre results day i had opted for psychology, i had changed to chemistry in the final options choice. i went to the head of sixth form, and she quickly changed me to chemistry, because i did get AA in double science. however, i’m thinking more into this- in year 10, we did unit 1 and i barely scraped a c (had a lot going on), but in yr11 i got a fairly solid a. the grade requirement for any science is BB, and biology (a*,a) was not a problem. am i thinking too far into this, and it was a simple mistake, or do the teachers believe i’m not qualified to do a level?
