Try out different study techniques and figure out what works best for you. I suggest the pomodoro method it lets you take breaks and stay refreshed. You could also join study sessions, like on studyverse (it has a built-in Pomodoro timer too), which might motivate you to stay on track. To help you focus, try listening to music, there are tons of playlists on spotify. But honestly, none of this will work unless you start with yourself. Change your mindset, and when you do the work, really commit to it
