Hello aspirant,

The Marks vs Rank in SRMJEE defines the rank with respect to the marks you obtained. For a  particular range of marks the corresponding range of ranks are declared.

It may not be sure that the cut off will increase. The cut off varies every year with respect some aspects such as number of seats available per branch, varies from one campus to other campus. It may increase or decrease as per above aspects.
