Hello,

EWS stands for economically underdeveloped sector. A household must have less than 5 acres of arable land, a plot of less than 900 square feet, or both to be classified as EWS. ft under a municipality, a 1,800 sq. ft site outside of the city limits and a property of less than 1,000 sq. ft space.

The EWS certificate is still valid for up to a year.

So, as per your query it will be valid if you going college this year.

Thank You
