B.Sc

Both courses are same only the name of the degree is different.

The college has got average rating, so you can get into it for B.Sc agriculture.

B.sc Biotechnology is better than B.sc architecture.
More scope for Biotechnology nowadays.but with 63% marks it will be a little difficult to get admission in a good college though.but can apply for management seats but a little expensive.

You are eligible to appear for CDS exam conducted by UPSC for selection of Commissioned Officers in three services. You may opt for Flying branch.

There wont be.there are so many job opportunities in private and govt. Sectors.all the best

After completing B.Sc, you can go for further studies like M.Sc. or MCA or MBA. But if you are interested in Government jobs then you should prepare for Government Exams like - IBPS PO, IBPS Clerk, SSC CGL, Railway Exams.
In these Jobs the salary is high & these jobs are very comfortable.
