I have found studying to be easier for me when I go to the library rather than stay at my house. I don't know if that's possible for you. But for me it creates fewer distractions. Related to another post, I'll go to a computer lab and plug in head phones with classical music or something else and then spread my books out and sit for hours studying.

Also, maybe download Insight Timer, a meditation app, to your phone. When you get distracted you might try meditating for 5 or 10 minutes to clear your head and then go back to studying. Just a thought.

Best of luck.
