Scottish Advanced Higher Topics

I'd like private tutoring!
A2 is 100% harder than AS. You have the opportunity to achieve a new grade, A*, for your A2 modules. In order to achieve an overall A* grade you must satisfy 2 independent criteria:

1. Get at least 80% overall average across all AS and A2 modules. For example 70% in AS and 90% in A2.

2. Get at least 90% overall average across A2 modules only.

So someone who got 90% in AS and 89% in A2 would not satisfy criterion (2), hence they would only get an A. Someone else who got 68% in AS and 90% in A2 would not satisfy criterion (1), hence the same would happen. The latter scenario is extremely unlikely because, as I mentioned, A2 is significantly more challenging than AS.
