uh
suck it up and just get things done? like i know it sounds tough but its going to get harder when you are faced with multiple projects at once in the future so start breaking all your projects down and allocating sufficient time for each of your subs!
starting is definitely a good place, but if you don't know where, just make a list of things you need to do for each subject and make sure you get those things done? you actually have plenty of time if you don't procrastinate and work diligently
idk it also depends on the nature of your assignment as well
