I am doing my information science engineering but I don’t even have the basics at coding.Now this is my second year back .Should I continue doing engineering? Or join other course?

Firstly,see the reason of your backlog.It may be your lack of interest in your stream OR it may be your lack of enthusism for learning and hardwork. If it is lack of interest then try to take interest in the field since the interest of human beings changes through the life. So there is possibility that you will start taking interest in Information Science and get success in it. And if,even after deliberate effforts to take interest in the field you don’t seem anything inetersting in Info Sci and you just dont like it then leave the course.Choose something which you like to do.Secondly,If you have interest in the field but just can’t do it then take it as a CHALLENGE TO YOURSELF and start from basics of coding.You can take guidance of teacher or online program or YouTube .It is not impossible.You can be a expert coder.
