Need Guidance

I am planning for M.Tech,I'm not sure whether I should go for it or not. Let me tell you my condition so you can guess better.

I'm a Software Engineer doing QA at product based company earning enough as a fresher to have good life in Gurgaon(it's 9LPA fixed), but not satisfied with the work I'm being alloted.

I think I can upskill better If I have some more time as in college days.Yes I want to make big in life which I think is easy if I have good college background(something like going abroad for opportunities)

Confused whether in M.Tech I will get free time as in B.Tech or I should continue my job and switch as developer in another Company?

I'm confused whether I should continue this career or not?

(May be these thoughts are because of Monday)
