Exam tips: how to score higher in General Science and Emerging Technologies
Where students lose marks: attempting questions they have not truly eliminated options for, spending too long on one hard question, and rushing the sections they know best. Read the whole paper first, bank the marks you are sure of, and come back to the rest.
Manage your time and guess carefully: split your time in proportion to the marks each section carries and keep a few minutes at the end to check. This paper carries negative marking, so attempt a question only when you can rule out at least one or two options — a blind guess costs you marks. Confirm the exact marking scheme for your session on the official portal.
