Hello Aspirant

The replacement of marks in the 12th Mark sheet depends on a lot of things. If English is one of your first 4 subjects, then no, you cannot replace your English marks with IT marks.

If you are applying for a BSc Computer Science course, then yes, you can replace your English marks. But still, your English marks will be looked at because you are studying in an English medium institution.

If you are planning on pursuing a BA course, your English marks will be of utmost importance.
