O Level Chemistry


Hey guys, just a disclaimer, although the title states "O Level Chemistry", this is only my Sec 3 notes since I'm currently Sec 4 this year... so yes, it's incomplete O Level Notes. Also, even though my notes for these chapters are 76 pages long (in google docs, microsoft words is 70 pages bc format different), i included quite commonly tested questions as well as questions that i didn't know how to answer. Every pointer (not in tables) means that the point is either 1 mark or 1/2 mark. For the tables, the pointers are just description points and does not serve as an indication of the marks oops... Anyways, I hope everyone can take your time to read my notes on CHEM and feel free to edit it because I've saved it in a microsoft docs (can save to google docs too but they're comments there e.g. "look" which means the answers i'm not very confident in :/) form :) All the best!!
