G2 SEC examination strategy improves when learners preserve useful options while uncertainty is still high. An exact value can be kept before rounding; two plausible referents can remain open while context is checked; a hard question can be parked with a checkpoint instead of abandoned or restarted.
This one-hundred-and-thirty-second Learner’s Guide develops option value across K200 English, K210 Mathematics and K223–K225 Science. It follows Vol 0128 Reversible vs Irreversible Moves and Vol 0100 Checkpoint Compression.
The option-value test
An option is valuable when it is cheap to preserve, uncertainty is meaningful and later information can distinguish the alternatives. An option becomes clutter when preserving it consumes more time or attention than the decision is worth.

For expensive option preservation, identify what future information could make the option useful. If no plausible future evidence can change the decision, close the option instead of carrying it indefinitely.
For practice, compare premature commitment with disciplined option preservation. Measure the cost of keeping the alternative alive: extra notation, time, words or working-memory load. Preserve only options whose potential recovery value exceeds that cost.
Once evidence clearly favours one route, commit and clear the unused branch. Option value is not a licence for endless hesitation; it is a method for delaying costly commitment until the uncertainty that matters has been reduced.

Option value changes during the paper
Early in a difficult question, preserving alternatives can be valuable. After a discriminating clue, verified calculation or hard constraint appears, the value of the losing option collapses. Good examination control therefore closes options dynamically.

Final rule
Preserve alternatives when they are cheap and future evidence can still matter. Close them when the decision is sufficiently supported. The goal is not maximum optionality; it is the right options at the right time.
