difference between AS level and AlevelWatch
A-level (Or A2) = second year
Typically AS is worth 40% of your alevel grade and A2 is worth 60% (hence more papers in certain subjects)
Hope this helped!
If you do take AS exam, they don't count for university applications if you then take the same subject at A level. If you have a UCAS points offer then an AS grade (in a separate subject) get you 40% of the UCAS points of the same grade at A level.
The total exam length of A level papers is about twice that of AS exams.
