I would not recommend any one to opt this subjects if they are blank in it. Well you can pass this subjects with ease becuase objevtive part is eas, but to secure well in this paper u need great knowledge of subject. Syllabus is lengthy but easy. You cant skip any part of syllabus,that is suicidal.
Well go through the past papers of ce16 and 17 and if you think you can do it. Then go ahead. Wait for dmcs to check performance of rhis subject.
