U should have gone for btech earlier. U hv to pursue graduation in engineering. Then u will be eligible for gov jobs also. Indian railways, bsnl notifies job vacancy for diploma holder. U may study hard to crack one of those exams. All the best.

There are certain institutes in kolkata where u may opt bsc. st.xaviers, presidency, jadavpur, scottish church, institute of genetic engineering(affiliated under wbut), serampore college (affiliated under c.u), ashutosh college, shri shikshayatan (female) to name a few.

Yes, u r eligible fr b.com curriculum if u hd maths in 12th. See there is no special job oppurtunity doing bcom. Ya, u may get junior accountant post in small firms which are of very low salary. Better would be, if u pursue mba after completing graduation in your own stream subject. That will surely drive you to the right job. All the best.

12th is better, because in 12th class you got the complete idea of all subject basics. Your first step is to join a reputed coaching institute. Once you do that,just follow the advice of the professors there.Be prepared to study for 3 hours daily. Basically, you should pick up some good standard books and start studying from them.
