Yeah! You can use blank sheets for doing roughs but do not take notebooks as this can be out of the disciplinary guidelines of the SRMJEE. Also you should not be with any books or any other devices and obviously with no other person in the room for the examination. If any of this are found then they may take disciplinary measures against you which can lead to cancellation of examination.

Be careful and sincere while giving exams.
