Why do children who understand Science still lose marks?
Because the paper marks the answer, not the understanding. A child can know exactly why the plant died and still score zero for writing 'no sunlight' instead of stating the relationship the question asked for. The open-ended section rewards a specific structure — identify the factor, state the effect, link the two — and children who are never taught that structure lose marks they have genuinely earned. Next Level Enrichment drills it.
