We have 1 period in S1 and 1 period in S2 with most S1/2 (split with business teachers). We have 3 periods in S3 and 4 periods in S4 (they have to choose Computing Science in S3 though).
We go down to 6 subjects from 8 in S4 so they can drop it then.
Numbers went up this year from last by 2 classes in S3. Almost all S3 kept it for S4. More coming into Higher next year too, and some Advanced Higher.
