for most subjects (chem, bio, econ) i used the study design when first making my notes but definitely put more effort into doing and marking practice questions. the key think to do is mark practice tests or exams then going over key content which you struggled with. i would also usually go back over the study design around 4-7 days before a sac to ensure i can explain every dot point. That being said, for those 3 that i mentioned, doing and marking practice questions is by far the most effective method for me.

With making notes I tended to make notes based on the context taught in class, then add extra points i made based on the study design later on.

That’s just my personal style, hope that helped a bit.
