I'm 17 and I took a summer class to get ahead. The problem is, I simply am unable to study correctly, mainly because of distractions (my electronics)

I only have Snapchat and Youtube as "distracting" apps on my cellphone, but they still distract me too much. As for my laptop, I charge it in my bedroom, because I need it for online class in the morning. I installed a Website blocker on chrome to focus during class, but I always end up turning it off and wasting my time. I try not to charge my phone in the bedroom, but I need it as an alarm (I'll buy an analog clock soon.)

Any tips on how to study better and get rid of my devices addiction?
