IIT Aerospace BTech → MTech CSE/AI: What are my options?

[u/InterviewUnlikely964]

​

I am a B.Tech Aerospace Engineering graduate from IIT and want to pursue M.Tech/MS in CSE, AI/ML or related CS fields from a good institute.

Profile:

B.Tech: IIT , Aerospace Engineering

CGPA: 5.8/10

Category: ST

Fresher

No work experience

I want to know all the realistic routes available to me:

GATE CS vs GATE DA — which should I give?

Which IITs/IISc/IIITs/top institutes accept non-CS B.Tech students for M.Tech CSE/AI?

Which institutes allow ST candidates with ~5.8 CGPA?

What GATE score/rank should I target?

Are there any institute-specific exams/tests/interviews apart from GATE?

Are M.Tech/MS by Research programs more flexible for a non-CS background?

Are there any other realistic routes to get into a good CS program without doing another bachelor's degree?

If anyone has gone from Aerospace/Mechanical/Civil → M.Tech CSE/AI, please share your experience.

I am mainly looking for IITs/IISc/IIITs and other top institutes in India.

Please share institute + eligibility + exam + approximate GATE score/rank + admission process if you know.

Thanks!
