Hey hardik,
this is the most common problem for students nowadays. To improve your concentration most important is to have focus on what you are doing. Make targets of what you need to do. Make them in a daily basis And complete it anyhow. Make yourself disciplined in a way that you don’t sleep before completing it. Also try meditation to increase your concentration. And try not to use phone, laptop, etc much.
