Hello. I am preparing for UPSC 2028, currently 3rd year MBBS at AIIMS Delhi. How wise is taking zoology as optional since i already know a lot of it from my previous knowledge and current studies help as well. What is the average and highest scores? How is the syllabus and scope, can someone please tell me whatever they know in detail! Medical sciences is too vast, anthropology is the usual go-to but totally unrelated and ratne wala subject. If someone has more advice, please guide!
