Hey, I'm doing the same exam as well!
The topics which I think would come up would be:
The reflex arc
Synapses
Phototropism
Different forms of respiration
Stem/Unspecialised Cells
Producing Proteins
Good luck!

When you say producing proteins, do you mean the whole DNA/mRNA and ribosomes procedure?

Praying for the B4 question to be either on quadrats/light meters or different types of respiration, or maybe the different types of cell structures. Hoping B5 will be phototropism, really easy.

Yeah, how one strand of the DNA is "cloned", the mRNA goes to the ribosome, and so on...

predictions for B4
- enzymes
- different types of diffusion
- field studies (e.g quadrats)

predictions for B5
- making proteins..?
- cell division
- phototropism and plant development
- meristem and how it works

annnnnd i had no idea about b6! does anyone have any ideas for it?

Oh true! That'll be a good one. I was thinking there will be a question under B6 about memory models? I don't see those questions often.

I think I did pretty good in the exam... What about you guys?
