For me it's proton NMR and 90% of transition metals that are going to ruin me
I'm exactly the same with NMR and transition metals. Personally I've found writing out the reactions of each transition metal with the colours underneath a few times a week has been the only way I've been able to remember them, but I can't sugar coat it - it's so tedious! I've yet to find a method to learn NMR though!
Finished A2 2 weeks ago, took me 2 months to get through everything intensively. Been getting A's and the occasional A* in past papers which is nice too.
was wondering how to 'learn' mechanisms? i always get confused is it best to actually understand whats going on as i've never really understood the theory behind that lmao or can u just memorise the diagrams and what to write (if writing is necessary)
People told me it was the worst as there was loads to remember but I soon realized Born-Haber is just Hess 2.0, the period 3 reactions just a slightly deeper insight into AS periodicity stuff.
Remembering colors/formulas of transition metal complexes is somewhat tedious, but just like the organic pathways in CHEM4 the only way you get better is by going through it over and over again until it becomes second nature.

How many hours per unit would you recommend? I'm resitting CHEM 1, 2 and 4 this summer and I dunno how many hours per unit
Hard to say really, I devoted a day of studying to each "Sub unit" so generally 5-6 hrs. My routine was to watch as many revision videos as I could on the subject, whilst making some condensed but good notes and then going through some exercises on A-levelchemistry, going back on anything I didn't understand/get right.
