Human Anatomy and Physio 2 and Intro to Medical Biochemistry

Hello! Just wanting advice on ONPS2423 and BIOL2530 for semester 2. How hard is anatomy? and how similar is the biochem subject to year 12 chemistry? how can i do really well in these 2 subjects? I did a subject similar to Human anatomy and physio 1 last year at a different uni and so got credit for it this year. Tbh I've forgotten a lot since then so just wondering how difficult pt 2 will be.
