Hi,

Hope you are doing well.

If you get a score of slightly more than 130 ie 90-94 percentile in JEE Mains, you will be safe that is you will get admission at MEC. MEC's cut-off marks change year to year and are determined by the JEE Mains qualifying cut-off marks. In addition, each branch has its own set of cut-offs. CSE and mechanical has the highest cut-off in general, followed by the other branches.

Hope this helps.

Good Luck!
