For some people, it is very hard to concentrate on something that they don't enjoy doing, such as homework. Unfortunately I am one of those people. I find myself ways to concentrate such as closing all the lights and only leaving my desk-lamp open so that my eyes will not get distracted by my surroundings. I Also clear away all the clutter that is on my desk and I close the blinds so that I won't space out when I'm staring out the window. I Also use a timer to see how long it will take me to finish X amount of work so that I won't slack off. Also, I am continuously writing thing down no matter if they are notes, essays, or mathematical equations, it will help me focus on my work. Also I try to forget about any problems that might be happening to me at the moment because it might make me space out while thinking.
