Hello

I am opting for this subject too for the upcoming examination. While I haven't seen any DMC, most of the people I have talked to maintain that it is a relatively easy subject to prepare for.
Furthermore, the syllabus post 2016 is also far more specific and gives concrete topics and sub-topics to prepare. Whereas prior to this it was very open ended.

If you gain access to relevant DMCs please do share here.
