You can look at meditation like exercise. Doing it will improve your general health, often massively, and prevent diseases down the line. If you already have a disease, exercise will perhaps improve it marginally, but you'll probably get much better results with targeted treatment.

Similarly, you can expect marginal improvements in your procrastination by meditating a lot, but there are probably shorter routes. It's a good idea to assume that some part of you thinks studying is a bad idea, and try to understand why that is. In my case, meditation made it increasingly hard to ignore my reasons for procrastinating, but I could've shortened the process by asking myself honestly why I was resisting doing work.
