I have been advised, by multiple teachers, to once go through a-level papers because a portion of the O levels exam relies heavily on them. I'm not so sure if this is true, but some of my teachers back at school made our class solve those papers, and I think they are really helpful. Plus, I find them very intellectually stimulating! Of course they weren't the exact papers but simplified versions of them, any part that could not simply be solved by rational thinking was ignored. I'd really appreciate if anyone here would upload a few questions from Alevels which seem relevant to the current O level (Bio, Chem, Phys, Math) syllabus. P.S: Questions from any of the aforementioned subjects would be appreciated, but as of now, I’d like biology questions a lot more Thank you!
