Why can't I concentrate on my schoolwork?

Honestly? It's probably boring. But let's assume it's not boring. Or that it is but you need to concentrate anyway. Lots of things can get in the way of concentration: stress, depression, anxiety, tiredness and trouble sleeping, problems with friends or at home, attention deficit disorder (ADD & ADHD), and the list goes on. You might just have a lot on your mind, that can also make it hard to concentrate.

its said that concentration skills waver after 20 minutes, so study for those 20 minutes then take a small 5-10 minute break! its an effective way to learn. also, make sure the environment you're in is comfortable and quiet, unless you enjoy background noise. and finally, make sure to stay hydrated and not be hungry :)

The pressure of school work can sometimes get to everyone. Take a deep breathe and try some relaxation techniques. A relaxed body will encourage a relaxed mind! :)

yes school work is boring sometimes but we have to do it ,you lake concentration because either your not interested in study ...develop interest in study so you can concentrate in your school work ..

Maybe your mind isn't ready to work at the moment. Try again later,without any distractions in your area.

There could be many reasons. One could be that you just aren't interested in that particular subject. If it happens in every class and becomes a problem on an everyday basis I would seek professional help to see if it could be ADHD.

I often can't concentrate on my school work when I'm stressed, anxious or if there are other things on my mind. It helps me when I'm in a right frame of mind whenever I do school work. So to help I either try to relax just before starting to work as well as meditating at the beginning and end of the day

Maybe it's because you have too much on your mind or you're too distracted. You could try short blocks of time, like half and hour, of full concentration. Just sit at your table, remove all distractions like storybooks, computers and phones. For that half an hour, dont leave your table. Afterwards, you could reward yourself by eating something you like or using your phone. Schoolwork might be really boring and hard to do, yes. Think of it as a challenge and try to overcome it. You could also try to clear your mind and relax before starting on schoolwork.

Because you are focusing on other things which are not important, so what I always do is wear a rubber band around my wrist and whenever I don't concentrate or get out of focus I snap it to make myself snap out of it

There must be something or some thoughts which is or are not letting you concentrate on your schoolwork or maybe causs of just lack of motivation.
