Study.
Well that depends on you. Some people learn better with noise and music. So those people should study where they can play music and where there will be noise. If you are someone who is easily distracted, you should study in a quiet place that is not full of distractions. For example; the library. Whether you learn with noise or not, you should study in a place where it makes you calm. You should not study somewhere where it will make you feel uneasy.
