    Hi!
    Last year I averaged exactly 90% across my AS level in CCEA chemistry
    This year I need an A, so will I need to average 80% this year? 70?
    Also I know grade boundaries tend to be lower for the A2 written modules so if I averaged 70% in those and got full marks in A23 practical module how would that fair?
    Thanks if you can help, even hypothetically as I know boundaries are subject to change with scaling.

    You need 70% this year as you need 80% over the 2 years combined to get an A. It's only for A* grade where A2 is considered independently from AS (I.e. You need 90% at A2.) However remember these are UMS percentages. An A* in last years A2.2 paper (108/120 UMS) required only 91/120 raw marks which is around 76%. However that paper was also a difficult one but I'd say at A2, getting roughly 75% raw marks should secure an A grade and on average about 85% could secure an A* for the average "quite tricky" paper. Hope this helps and you should defs aim for A* if you got 90% UMS last year 🙂
