Choosing G1, G2 or G3: A Parent's Guide to Subject Levels

What the three levels mean

The word to hold on to is "in that subject". These are not labels for a child. They are settings for one subject at a time.

The decision, in order

1. Start from evidence, not hope. Look at the last two or three assessments in that subject, not the best single result. A child who has been scoring in the 50s in Mathematics all year is not a G3 Mathematics candidate because one topical test went well.

2. Work backwards from the post-secondary course. A Junior College science track needs core subjects at G3. A polytechnic diploma states its own subject requirements. Find the requirement for the course your child actually wants, then check which levels it implies. This single step resolves most of the argument.

3. Count the cost of overreach. A subject taken at a level above a child's current standing does not merely produce a weaker grade in that subject. It consumes the revision time that the other subjects needed. Under L1R4 from the 2028 Post-Secondary Admissions Exercise (PSE), which replaces the JAE for SEC students, where five subjects are counted rather than six, that trade is more expensive than it used to be.

4. Decide which subject is worth the fight. If a child is a genuine borderline case in one subject and can be brought up with focused teaching over two terms, that is often worth doing. Trying it in three subjects at once rarely is.

When moving a subject down is the right call

Parents resist this, and often should not. Moving one subject to G2 is the right call when it protects the subjects that decide the post-secondary route, when the child's results in that subject have been consistently below the level's demand for a year, or when the stress of carrying it is visibly costing them elsewhere.

The certificate records the level honestly, which means a strong G2 grade reads as a strong G2 grade rather than being hidden. A student who takes a realistic level and does well in it is in a better position than one who takes an aspirational level and does not.

When to make the call

The main decision point comes at the end of Secondary 2, with confirmation at the start of Secondary 3. That is late enough for real evidence to exist and early enough for the choice to shape two years of preparation. Schools set their own review points, so ask your child's form teacher when the window is.
