I'm a final year student and i have no senior to guide me

hello, I’m a final year student and i have no senior to guide me. I have marrow, can anyone tell if i should go ahead with marrow for medicine or should i buy prep ladder for deepak sir. Thanks

Stick with one source
You have ample of time
Try to complete topics which are HOT i.e asked in past 3 years
And keep clear concepts
Enough for you for final year and focus more on practicals
