Attn: H1 Bio students
The calculation of MSG is as follows:
2 (Sum of all H2 grades) + (Sum of all H1 content-based subject grades)
2(No. of H2 subjects) + (No. of H1 subjects)
2(No. of H2 subjects) + (No. of H1 subjects)
Of course, if you don't take a H1 subject the calculation is reduced back to the familiar way of calculating MSG in the past.
Hope this information will chart a clearer direction for your stormy voyages through the Sea of Revision ...
