I know how you feel! I always seem to have these bursts of motivation at the wrong time completely. By the time it gets to an environment that would be suitable for studying or whatever it is I wanted to do... For me, I have to somehow remind myself of my goals constantly, what I want to achieve, a plan in getting there. So I write it EVERYWHERE. I have a white board where I write all my goals, on my phone, I have my friends peppering me all the time whenever I'm on social media.
This might sound a little strange, but I study better in loud environments, where I can look around and see that no one else is studying, and that motivates me to study because I'm competitive and want to beat all those people.
But everyone has different study habits. So I'm not sure what would work best for you... All the best for your exams though! :) I know you'll be able to do it!!
