Answer 2

Putting your concentration in studies is not easy, I can tell by experience. If you are getting diverted, then close your book and take a short-break. You can resume studies after you feel refreshed again. Taking in small nibs of food in a while is good too, especially dark chocolate. Not saying you should eat your lunch and dinner combined all together, just tiny snacks, the most preferable being dark chocolate. Try to make your studies interesting by comparing it to everyday things, it will make you want to study more. Listening to some relaxing yet not-so distracting music can help you too, you can try out the Chillstep 2016 Mix, which is amazingly relaxing.
