I've always had a problem with procrastination mostly because it's a vicious cycle. I have found, in the past, that I'm usually just fine doing things just before they need to be done. That reinforces the idea that I can slack off until the last minute. I can't do this here. The best thing about this productivity hack is that it is totally customizable. This is usually a year-long thing, but I only really needed it for the following 80 days, and it converts really well to that. Plus, you can set how much time you want to spend on your activity of choice or you can have multiple calendars for multiple activities that you want to accomplish everyday, like if I were to add exercise, I could print up a separate calendar for that. As is, my calendar is pretty innocuous so I can add the X's directly to it.
I roughly calculated how many hours I need to study to be successful on the exam and divided that by the number of days remaining until my exam minus vacation days. I allotted myself a prorated 4 days of vacation as based on a typical 3 weeks of vacation for a year so 4 days of vacation for 80 days (~5.75% of your total time).
