According to the new updated pattern from 2018, there are separate papers for DM neurology, Mch Neurosurgery, and MD psychiatry courses.
The 70 marks paper continues. The questions are asked from all 19 subjects. The questions are asked randomly. The weightage of any subject is increased at any time. No fixed weightage from the subjects can be expected. Don’t leave out any topics from the 19 subjects. Each mark counts and can be the reason for selection and non-selection. Only 4 seats for DM and 4 for MCh.
For 30 marks separate papers-
Neurology: Neuro medicine is asked mainly. So it's important to read Harrison's neurology portion. You should have good concepts of Neurophysiology, neuropathology, CNS pharmacology, Neuro-ophthalmology, and a few neuroanatomia. Ketzung for CNS pharma part and CNS pathology from Robbins is recommended.
Neurosurgery: Mostly basic questions are asked. Good concepts of Neuroanatomy is a must. Snell and Neuro medicine from Harrison is equally important for neurosurgery. A head injury from Bailey/ Sabiston is recommended.
Psychiatry: Kaplan and Saddok is a standard book. Cover Schizophrenia and depression topics from it with the psychological examination. Praveen Tripathi's psychiatry reference book as a whole is helpful. Understand concepts well. Watch Caplan videos on behavioral science for a good understanding.
