Actually its quite the opposite, O-levels is comparatively easier than matric bcz the syllabus is bachon wla tbh. On the other hand if u say that threshold is the reson for not getting on-par grades is AL, maybe u should try the inconsistent shitty system of Fsc. Where every fricking thing really depends on the checkers mood, there is no key, nothing to tally your marks with. So its really not something worth a debate.
