Hello dear,
It depends upon your interest if you want to be in technical field than go for btech then m tech..
If you wants to be in business field than go for btech than MBA..
All depends upon your interest...
Best of luck

I will suggest you to go with mba
Since you find some subjects difficult
So it will be hard to do mtech

Also mba will get you good package

Good luck

Dear Shrushti
if you are not interested in the core subjects of your branch, it's better to go and opt and also in MBA you do have so many options
Google definitely helps you but according to my view, HR, marketing, finance are in demand now.
Choose decision wisely.
All the best.

All the three would be best choices.....but it totally depends on your own interest....if you are not interested in programming then you can to MS/MTECH from ece,mechanical,electrical branch.....MBA would also be a best option....so take your decisions wisely...
