To the students of IAS Gurukul, i wish you a very bright future ahead. Pranay Sir’s strategy definitely works in the examination.
Answer writing is a very important part of this examination, for sociology specially because it is a writing intensive optional. You need to get into the groove for answer writing..so that you answers can be to the point.. Interaction is also a very important aspect because every student learns at his own pace, every student has different requirements. (He can't help you) unless you convey to the teacher what exactly are you expecting of him, what exactly are the points where you are getting stuck.
I would say that interaction and answer writing are both very important part of your preparation. My best wishes are with you.
