NOTE: N20, M21, N21, M22, N22 grade boundaries were artificially low due to COVID.

NOTE: Beware of using outdated grade boundaries. Many subjects have since updated their syllabus.

NOTE: As a general trend (may not apply for all subjects), Timezone 2 usually have higher grade boundaries than Timezone 1. Make sure you use the correct timezone.
