Hello,


To make a career in computer and information systems(CIS),you will have to persue a bachelor's degree in this field.The stream you have choosed in 12th is good and relatable for this degree.
For jobs in banking sector you have two ways.Either you will have to crack the banking exams like IBPS or SBI or RBI.These exams are generally divided in 3 phases which is pre,mains and GDPI.The other way is tp enter a private bank and after graduation but you will have to work a lot there to get a good pay and promotion.

I hope this helps.

Hey aspirant, as per your interest you can either do BCA that is Bachelor in Computer Applications or opt of B.tech in Computer Science/ Information technology.

Since you are doing your 12th class from PCM, the above-mentioned courses will be best for your interest. You will really enjoy learning in your Under Graduation. 

For the banking sector, you can give various bank-related exams like Bank Po and IBPS after your UG.
