Answer:
if you want to study better I would advise you to not be in a comfortable situation while studying cause that will make you lazy,so it's better to be uncomfortable so you can study adequately,the other thing is you must have a motivation to study( think of what you wanna be as you grow up or what you want to contribute to the society),another thing that will get you going is making yourself guilty of not studying (what I mean by this is to think of your friends out there who might be studying while your not) and also turn off other app notifications so that you don't get disturbed..and lastly be in a quiet place.
I hope this helps,if they aren't enough please send a text in the comment section.
