With a GATE score of 549 in Data Science (DA) , you can target several reputed institutes for M.Tech admissions, though top IITs may be out of reach for general category candidates.

Where You Can Apply:

• Newer IITs (like IIT Jodhpur, IIT Bhilai) may consider this score, especially for reserved categories.

• Top NITs (like NIT Trichy, Warangal, Surathkal) offer Data Science or AI programs, and your score is competitive for some of them.

• IIITs like IIIT Bangalore and IIIT Hyderabad have DS programs. While IIIT-H conducts its own entrance, IIIT-B accepts GATE.

  Recommended

• Other universities (e.g., University of Hyderabad, DTU, JNU) also offer good programs in Data Science and often have lower cutoffs.

• 
  

1. Check institute websites for past cutoffs and eligibility.

2. Apply via CCMT portal for NITs and through COAP for IITs.

3. Consider category reservations if applicable.

4. Keep backups like state universities and IIITs in mind.

Your score is decent for several good institutes—apply smartly and widely to improve your chances!
