Hi. In order to get admission for a civil engineering course you must have completed 12th std with scienece stream with maths. Thereafter you will need to clear an engineering entrance examination- either the all India engineering entrance JEE or else entrance exams meant for the university or college you are aiming for. You can start by opting for science stream with maths now and preparing well for the entrance. 

Hello dear student

You cannot pursue engineering , be it civil or some other right after your class 10 as engineering is a graduate course and for that you need to be at least 12 th pass and without that you will not be get into any kind of engineering dear .
