Hi there,
So I would make a clear, and strict timetable that you MUST stick too. You could use the Pomodoro technique (google it) to make sure you are working efficiently by taking regular breaks - in this time you can 'procrastinate' in any way you usually do, and then get the work done in the other times!
Be sure to devote a good amount of time to all 3 assignments - it is better to say score 60 and 60, 60, than to score 35, 40 and 70...
I'm sure you can do it - good luck!
