Use outlook calendar. You most likely already have it with your MS office suite, and with a little cuztomization, you can remove all the other features like mail etc and force it into calendar only mode. Sync this with your phone and it's perfect (though even only on laptop is enough too).
Using digital calendars is so much better + easier becuase trust me, you're gonna keep moving tasks around when you realize your deadline was a joke and can't work on something till the next week ...etc.
And with outlook, you can easily use the categories feature to seperate things like midterms from tutorials you have to prepare for, use a seperate colour for labs that need to be written up, and one for papers you have to work on, maybe even plan out all your readings (which you'll keep moving becuase you will never do them
)
