BBA

To get a government job, you don't need to do any other course. BBA itself fulfills the eligibility criteria which is that you must be a graduate.
There are many government exams, you can join a good coaching and prepare for them.
Some of the prestigious exams are -
UPSE
CDS
SSC CGL
IBPS and SBI PO
Indian Railways
Good luck.

BBA graduates get an entry-level supervisory and junior management positions in various types of industries in different management functions. In order to grow in career, a BBA graduate would require an MBA to move up the ladder. As you want to start a job in the field of accounting after BBA, you are advised to increase your employability by doing courses in Telly, SAP FICO or Advanace MS Excel XCEL etc.

BMS graduates can easily get entry level supervisory jobs in any industry in any of management function of their choice. However, for long-term career growth, they have to do MBA. If you are able to get good campus placement after BMS, you are advised to take up a job and after few years experience, go for full-time MBA, else you may opt for MBA immediately after BMS.

If you are interested in management then go for BBA and if you want to be a tax expert then go for CPT. It depends on your interest.

If you do dual degree MBA, you get struck with same B-School. It is better to do MBA after graduation degree so that you have choice of doing MBA from high (top) ranking MBA college. This will be helpful for long term career.

Quit this course otherwise you will regret for the whole of your life and also you will save your 2 years to pursue your passion or interest field. Go for BBA if you are interested in business. But, I would still say that if you don't have interest in business or BBA then complete your BE degree anyhow as it is better to have something than nothing.

Hi Shubham,
You can join in May or June in the same institution. You need to wait for next academic year.
All the best.
