Hi
I'm a girl of 15.and I really want to concentrate at my studies than it wander for some other useless subjets. Can it be possible for me to do this?

It absolutely is possible.

It takes a great deal of self-discipline and focus to study something you're not that interested in for a long time, so it's often better to break your studying up into segments. Depending on the material, they might be 20 or 30 minute study sessions, or longer 1 hour segments if you need to do more critical thinking and analysis.

Also - Remove distractions. Things that easilly allow your attention to wander, like a phone or an iPod.

And - Make sure you're getting enough sleep and eating reasonably well.

I agree with the previous.

Also, if you don't concentrate, you'll regret it when you're older. It's better to look back and know you put all your effort in, I promise.
