About OBG in UPSC CMS
OBG questions in UPSC CMS are clinical in nature, testing the ability to manage obstetric emergencies, interpret investigations, and apply correct management protocols. Questions on family planning, medical termination of pregnancy, and national health programmes are frequently asked.
Primary references include DC Dutta’s Textbook of Obstetrics, DC Dutta’s Textbook of Gynaecology, and Williams Obstetrics. OBG accounts for approximately 40–50 questions in CMS Paper II.
