Both are Hard, but Unit 4 is worse so tricky.
Unit 5 should be comparatively less harder, because its inclusive of a Scientific article which you prepare from early on and you kinda know the expected questions :P

I don't intend to scare you but yeah if you are doing bio as optional subject then I suggest you better drop it before you join A2!

and if you decide continuing then here's the suggestion:

I read up on lessons once I get home at least once every two weeks. I also ask even the slightest doubts I have (kinda annoyed my teachers lol).
There were instances whilst doing lessons when she would tell us how important a lesson is, and I would shorten form all that's needed. When there were paragraph worth descriptions I need to remember, I would find mnemonics really useful. Also, after every read up, I write out a summary through memory.
And finally, doing all the past papers, timed.
Also note, though these might have helped me, everyone has they're different ways of studying. Look up some more techniques. If you find certain ways really loathsome, (for me which would be short notes) don't do it. I found that it discourages me from wanting to do anything.
Good luck! xxx
Guys any predictions ?

hey everyone! i how would you control the temperature when investigating the effect of caffeine on daphnia?


You should use a water bath set at a particular temperature. (Yes I know I'm late, but hopefully you find this useful somehow)
