Should I drop 1 year or should I take admission in some engineering college? I got 48% in 12th but missed my JEE.

I would rather say don't lose your valuable 1-year and go for further study with UEM, Kolkata. Know more information about the college with this link: https://www.shiksha.com/university/university-of-engineering-and-management-kolkata-47398

Yes you have to drop this year as your 12th marks is low that any college depends 50% minimum marks in class 12th so appear for class 12th exam and give your best and score good marks.

Hello Juned, I don't suppose you can get admission in any college on the basis of only 12th marks. You have to appear for JEE after solving practice questions as many as you can, learn more and more concepts and keep revising the topics you find difficult. All the best for your preparation.
