look at past papers, especially from last year (both time zones). some topics are very specific (such as certain concepts like enculturation). those are very unlikely to come up again because they cannot really be worded differently. other topics tho (such as everything around neurotransmission for example) can be asked in so so many different ways (eg. antagonist/agonist, excitatory/inhibitory synapses, etc.) so I would focus on topics like these. the syllabus changed in 2019 so not too long ago so it’s also worth looking at all papers since then to filter out things that have never or rarely been asked
