hello aspirant,

in class 12 of studing take commerce as of your stream. after sucessfully completed your 10+2 you can do b.com or can do b.a in economics. while studying your undergraduate prepare paralley for sbi p.o, bank exam. and if you are really good in your academics you may go for CA (chartered accountancy ) courses. or after completing your gtaduation do some courses on tally, SAp WHICH WILL BE BENEFIAL TO do a job as business analyst profile in tcs, wipro, infosys like mnc. 

if you are ambitious and hard worker you can apply in CAT, and may get a chance to do MBA , master of busuness administration in finance. that will open a lot of career path for you.

hope you get my point.
