FWIW, I've found that regulating time inputs is very effective for me. I pair up a chunk of time with an assignment I can get done at that time, and then mark it in my calendar. That way I know exactly what I am doing when, and I can ensure I'm getting all my work done on time.

When the scheduled time comes to do an assignment, I treat it like it's a scheduled class lecture. (I'm kind of anal about always going to lecture, so doing the assignment feels non-negotiable as well.)

So yeah, definitely give it a try and let us know how it works out! :)
