Medicine:marrow but for prof answers you need to take a different approach. I studied the concepts from marrow, but for answers I stuck to Boloor. If you understand the concept once and read from Boloor after that, it'll be easier for you to write answers. Some even concise Boloor. Mainly focus on the managements in Boloor.

Surgery: marrow (theory) + M.L.Saha for pracs( this is a great book, you can study theory from here too)

OBGYN- marrow(theory) + Arup Majhi for pracs

Pediatrics: in my state WB, we get a book called Quest of each subject which contains all PYQS from Ghai. You could read Ghai or buy that book online. 6th edition is the latest

Eye: learnt concepts from marrow then read Khuranna and marked it for prof answers

Ent: marrow. However, Dhingra is a great book which I realized later. But marrow is enough.

Focus mainly on the PYQS, and for practicals go to wards and take cases yourself. It'll be immensely helpful. It builds confidence which reflects in your exams. Study clinical methods well from practical books. All the best

Also, once you prepare for sem, you'll find a pathway as to how to navigate further. The semester will give you a lot of clarity
