Dear student,

No change as such

There will be two question papers, each of three hours duration. Both the question papers will consist of three separate sections on Chemistry, Mathematics and Physics.

Questions in these papers will be of objective type. The answers for each of the questions are to be recorded on a separate specially designed machine-gradable sheet of paper (ORS – Optical Response Sheet).

While answering each of the questions the candidate is expected to darken the bubble against correct answer(s) using hard black (HB) pencils only. In some sections, incorrect answers may be awarded negative marks.
