First of all , u need to make whether u r really interested in your core courses.If yes,then u can opt for GATE preparations and do M.Tech. and if u r genuinely interested in certain stream,u can start preparing for GRE,TOEFL,etc and other foreign colleges admission but it really matters on your financial condition too.No dount,u may get scholarship,but it still is not affordable for everyone.
Otherwise,for MBA look for finance courses like principles of econmics,fundamentals of finance and accounting ,etc, and then make a call.If u like it and want to see yourself down th line as financial manager,HR manager,accounts manager,etc,then definitely opt for MBA.
Hope this helps!
