Does writing with a fountain pen in IAS Mains smudge the answer sheet?
The paper is of awesome quality. You can use whichever pen you want to write the exam. It won't make much of a difference. Except with a pilot V7 pen, which can drastically improve your writing speed.These things should not be on your list of concern at all. Rather try and focus on the task at hand, which is remembering, understanding, imbibing, internalizing, recalling and reproducing the correct factual & conceptual information, needed for clearing this exam. And there is a hell lot of it.
