The cutoff depends on the difficulty of the paper which varies each year, so, it would be meaningless to state the cutoff marks. What matters is the rank.

As per the AIIMS MBBS cutoff 2018, candidates belonging to General Category requires to score at least 50% marks in the Entrance Exam. While those belonging to OBC requires to score at least 45% and the SC/ST candidates need to score a minimum of 40% in order to qualify the exam.

Try to score 115+.

May your wishes come true. All the best !

In aiims eligibility criteria is 50 percentile. Aiims publishes rank and percentile. It is difficult to predict marks
