iAL Chemistry Unit 3 May7th,2015 - URGENT HELP NEEDED

Hello, I am probably screwed because I couldn't revise on time.
What I need to know is - what exactly is the list of experiments I need to learn for Unit 3? I know they are based on Unit 1 and 2 but what are the experiments in those I need to learn?
e.g. Flame tests for cations
Please, please, a list would really help! Thanks!
[EDIT] Question resolved thanks to @hmsafiya and @senshi1. The lists are below in the thread.
Here are some pretty good notes:

You need to know the flame tests.
tests for anions/cations
solubility of group 1 and 2 nitrates and hydroxides
tests for gases
carrying out titration
making halogenoalkane from alcohol (or the other way round :0 *panic mode*)

I hope this helps.. Goodluck.. Hope we do well.. fingers crossed
