hey! im in year 12 right now and im doing chem a level. we've just done a whole chunk of module 4 - all about organic chem, and i get some parts of it but others just really confuse me so much and there are so many exam questions i see and try and do that just baffle me tbh. does anyone know a good way to revise organic chem or any good resources they recommend using (any yt videos, or websites would be really helpful!!)
