Hello Michael,
I understand how crucial past papers are for effective exam preparation. I recommend exploring https://epastpapers.com/cie/cie-a-level/ as it is a treasure trove of past papers for CIE A-Levels, including Information Technology. This website has a comprehensive collection, and you may find it quite handy for your preparations. Additionally, consider checking related discussion threads or study groups on this platform, as they might have more resources or advice to offer.
