will we get any sheet for rough work in AIIMS 2017 MBBS exam?

If u go through aiims prospectus u find the info that u r allowed to do all rough work on the back of admit card only
But you need not to worry because aiims ques are not so lengthy that u would need to do lots of rough work...
Physics ques has 20 assertion reason ques which need no rough and among the rest 40 ques many ques are conceptual and related to theory
Their are only few lengthy numericals
Rest are easy so one page for rough work is sufficient
No one faces problem regarding space for rough work so don't worry

It depends on the examiner if he allows you to use rough sheet. But it is quite difficult to get the one from them but if you need it then you can ask for the same to your examiner.

Good Luck!!!
