To determine if you can reapply for the M.Tech program at Amrita School of Engineering Coimbatore in the same specialization, let's break down the key points:

- Eligibility Criteria: You need to have a minimum of 60% in your B.E./B.Tech/MCA/M.Sc in the relevant discipline, and a valid GATE score can offer direct admission.

- Application Process: You can apply through the Amrita online admission portal, filling out the application form and paying the non-refundable application fee.¹ ²

Considering you were rejected previously and didn't receive a mail regarding the next campus interview, here are possible steps:

- Check Eligibility: Ensure you meet the eligibility criteria, especially if you've improved your academic scores or obtained a valid GATE score.

- Contact the University: Reach out to the university's admission office to inquire about your previous application status and potential reasons for rejection.

- Reapplication Policy: Confirm if there's a restriction on reapplying for the same specialization within a certain timeframe.

If you're eligible and allowed to reapply:

- Update Your Application: Ensure your new application reflects any improvements in your academic profile, new test scores, or additional experiences.

- Prepare for Potential Interview: Even if you have a valid GATE score, be prepared for an interview if required.

Before reapplying, it's crucial to understand the admission committee's perspective on your previous application. This will help you strengthen your new application.

Good luck!!
