For a standard question that only asks about one thing (for example, 'Discuss Asch's research into conformity'), 1 AO1 paragraph with roughly 5-6 points is fine (in this example, a couple on the procedure, a couple on findings and a couple on the variations). I'd follow that with 3-4 AO3 evaluation points. If you're only going for three, try and make them developed points (for example, counterargue them or link to issues & debates, which you'll do in year 13).
For a question that covers more than one topic (for example, the one you mentioned about resistance to social influence), do one AO1 paragraph about one of the topics, then add your AO3 for that topic, then do the same for the next topic. The number of AO3s per topic depends on how many topics you're covering (you still want about 4 AO3s overall).
You can also use a structure where you talk about one AO1 point and then one relevant AO3 point throughout the essay, for example, using the Asch question I mentioned:
One short AO1 paragraph about the procedure used, then one AO3 about the ethical issues it raises
One AO1 about the findings, then one AO3 about the limited application of them, and one about the fact that the findings are less relevant in the modern day than they were at the time
One AO1 about the variations, then one AO3 about the artificial nature of the task
I found that once I learnt how to structure essays well, they were a lot easier to write and it was easier to figure out what was and wasn't worth including. I hope this helps!
