Dear aspirant,

The previous year cut offs suggest that you will be able to get MIMS if you score above 450 in the exam. The cut-off is highly variable and it depends on how difficult the exam is etc. Generally, mock tests are harder than the usual exam and thus going by that logic you must be able to score around 500 in the main exam easily. So, I would recommend you to keep preparing well and you'll be able to get admission in the college of your choice.

Hope this helps.
