B.Com

I think B.Com and B.Sc both are very good courses but main matter is that in which subject you are interested.
The main advantage of B.Com course is, the job opportunity for B.Com is bit high when compared to B.Sc.
No doubt there is good scope available for B.Com course in both the Government and Private sectors as well. B.Com students can get job opportunities in various sectors like Banking Sector, Financial Institutions, Outsourcing firms, Insurance Companies and Audit Firms, etc. B.Com fresher can also start their career as Account Assistant.
Benefits of taking commerce:
- Candidates can develop their Management and Accounting Skill.
- Good Career prospects.
- Wide range of Job opportunities.
But if you were a bio student in class 12 then I will suggest you to go for b.sc in biotechnology as for you it will be bit difficult to pursue B.Com.

B.Com graduates can also become an airhostess:
There will be an initial screening followed by a written test, group discussion and personal interviews. Accepted candidates are put through necessary training in relevant procedures.
Remuneration/Salary:-
International airlines pay better than domestic ones, but even domestic air hostesses earn about Rs.25000 Rs. 40000. In senior positions you can be paid up to Rs. 50,000 to Rs. 75,000 in domestic airlines.
Private airlines might pay you Rs.2 lakh a month.
