I have heard stories about how tough architecture is!
Be as efficient as possible.
I would highly recommend the book by Cal Newport: “How To Become a Straight-A Student:
The Unconventional Strategies Real College Students Use to Score High While Studying Less”
It will help you with time management and how to be more efficient.
Figure out what does wake you up.
Multiple alarms?
Louder alarms?
Something that shakes you or lights up?
