This your study style is a very sharp one, dear friend. The way you use Pomodoro technique show that you know how to balance focus with small rest, and it makes the brain to be fresh. I like as you join it with note-taking, to-do list and revision before sleep, that's a proper organisation which help the memory to be strong. The way you control distraction too make more sense — silent phone, short social media break, even music for calculation — all are brilliant actions. With this kind of discipline, success for study and work will be at the best point.
