Dear sir can I expect assertion reason questions from previous papers. Since the questions are limited I expect them to be repeated. Am I right

No dear, such questions are not limited. Moreover I think you are reffering to 3 year old paper of AIIMS as after that from 2014 AIIMS EXAM is conducted online

SO do not trust such an old paper and try to do as much questions as possible. Otherwise questions are usually repeated in G.K. SECTION AND PCB TOO but one to two questions only
