The Solution

Set up a proper study space: Find a well-lit, quiet study space and prep the area with all the materials you will need, such as pencils, pens, erasers, or a calculator.   Have a bottle of water and a small snack nearby, such as fruit or granola bars.   Make sure you're not watching TV or multitasking in any way, the work on your desk is the only thing you will be doing.   Set the room temperature to a comfortable level, not so hot that you're sleepy, not so cold that you're shivering.   Leave your phone in a different room and get to work.
