I'm also in a similar situation and feeling kind of hopeless. But I'm in my third year so i have some experience Something that has helped me a lot is creating a study plan where i plan everything I'll do in a day. I first counted all the days i have to my exam. I have 35 days . Then divided if by the number of topic i have in every subject

E.g I've done 16 topics in pathology for the whole year so that means each 1 week = 3 topics .

This really helps me but it's best to figure out what will work for you .

It is possible to learn all that info in a month just remember that exams don't test for everything so keep your revision high yield and try to keep a positive attitude you'll be surprised when you start revising how much information you already knew.

Good luck.
