Annotate the question!!! Annotate it MORE than you think you need to. Like write, like crazy. Obviously doesn't need to be full sentences, but you can recieve marks for content you put in your question annotation, if you forget to mention it in the response.
Just go through all of the dot points, and make sure you can speak about everything that comes under them, to a parent or friend. If you can dumb it down for someone else to understand, then that means you understand the complex information. (Cuz you can reduce the vital parts for some1 else).
Also plan ur responses (especially longer ones). Even if it takes a 30 seconds. Make sure you hit EVERYTHING. It's super easy to be rushed with adrenaline that you don't actually hit everything that you know.
Bio was a bit of a 'wing it' situation for me, as I ended up cramming pretty heavily the 2 days prior, so I'm probably the wrong person to ask for tips off hahaha.
GOODLUCK GUYS! You're so close to finishing wtf! It's flying by
EDIT: Just realised i sent that reply, as you guys are sitting the paper!! SORRY lol. Sending good vibes
