Hii,

Yes, a third-year student can join the NCC (National Cadet Corps), however it is subject to the specific criteria established by the institution or the NCC unit.  Most universities require students to achieve a minimum percentage on their academic tests, but this can vary.

To ensure eligibility, contact your school or college's NCC office.  NCC invites all students who want to participate in its activities, regardless of their academic status.

The official website of the National Cadet Corps (NCC) is indiancc.nic.in (https://indiancc.nic.in) .
