So I was searching YouTube for tips to study for exams. I got my internals coming up next week, so just like any other person on the earth I was searching for these useless tips and I found about something called 'White noise'. I don't know if it really increases your concentration level or helps you study things better without getting disturbed. This is a huge forum and many people post here so I guess anyone could tell me from their personal opinion whether it is worth or not. Also suggest me a good MP3 because there are many.
