You can never master this chapter without knowing the concept. The concepts might be a bit overwhelming while starting off. Being a dropper, I completely understand that you will lack time. However, with ionic being one of the pillars of physical chemistry, cannot be given the back seat. Therefore, I'd suggest you go back to your notes in case you have made some good notes during your first attempt. Otherwise I will share some good handwritten notes on your request. If this is not convenient, the best other option out there is Cengage. Read Cengage in and out and your concept for ionic is complete. Also, the questions in the back are also good. Don't read OPT.
P.S. didn't see that you had VMC Modules. VMC Modules are no doubt one of the best packages one can find among the major institutes in our country. I'm pretty sure ionic will also be good. However, if you can borrow Cengage for like 2 days just to read the theory part then I'd suggest you do that rather than referring to your module.
