This book has been written keeping in mind the needs of students preparing for various postgraduate entrance examinations and MCI screening test. Nowadays, mastery over short subjects has become key to get a good rank. In most of the examinations (including INI-CET and NEET), at least 5–6 questions are being asked from psychiatry. If students can spare 5–6 days for psychiatry, they would easily be able to get those questions correct and that will make a real difference in the final ranks achieved.
