Hiii Gulsher,

Yes,You can definitely be a civil engineer after B.sc! But you will have to work a lot for that.You need to learn some important topics of Civil engineering such as CAD. Apart from that you should have proper command on Mechanics.

After learning all these things, try to get an internship from any good company and after that apply for a job.

Another way to be a civil engineer is by clearing GATE and  pursuing  M.tech from any good engineering colleges in civil engineering.

Note:You can also do M.Tech in Civil Engineering without clearing GATE from Private engineering colleges.

All the best
