I can't say it will be best.
I rate it 3 star out of 5.

Dear student
As per your career path you should go for MSc in astrophysics and than go for PhD programme even very few universities do offer this specialisation .
And if you want to do M.tech than the require education degree will be B.tech or MSc level.
All the best

Hi
Yes, you can do bsc + msc and then mtech for physics related field. If you are keen to become an astrophysicist, check BS + MS courses at IISER or IISC. All the best

Are you being offered MTech under WASE program of Wipro? If yes then it is a right career opportunity for you. Because WASE is an eight-semester (4 year) off-campus collaborative M.Tech in Software Engineering program equivalent in status to the full-time 2 years M.Tech in Software Engineering degree program offered by BITS Pilani. BITS Pilani is one of the best Engineering Institute in India. This will give a very big push to your career.

No engineering institute in India runs MTech in UAV. However concepts of UAV design are covered in MTech Aeronautical Engineering. IIT Kanpur runs a short course on UAV.
