Eligibility for M.Tech admission while having a backlog can depend on the specific policies of the institution you're applying to. Generally, here’s how it works:

1. Check Eligibility Criteria: Verify if the institution allows provisional admission for students with pending results.

2. Provisional Admission: Many institutions offer provisional admission if you have cleared the entrance exam (like GATE) and are expected to clear the backlog before the final admission.

3. Result Timing: Ensure that your final results and documentation can be submitted before the final admission deadline.

4. Contact Institutions: It’s best to directly contact the admissions office of the institutions you're interested in to confirm their specific policies regarding backlogs and provisional admissions.

To ensure a smooth process, confirm these details with the specific institutions you’re targeting.
