I haven't been to a class in two weeks and I have learned so much more efficiently and have absolutely enjoyed my extra free time. That being said, without scribe notes and mp3 recordings of every class, there is no way that I would skip at all.
As it stands now....I wake up when I want, though generally limit it to 7-8 hours....then go to the library/starbucks/wherever and listen to the previous days' lectures (on my ipod), with the class notes and scribe notes in hand. Its like having a personal tutor. When the teacher says something that I miss, or is too fast to comprehend....I simply pause, rewind and repeat as many times as I need to fully understand and then I can write down my personal notes at my own pace. When I'm ready....I un-pause and continue with the lecture. It generally take around 2 hours to complete a 1 hour lecture, but because I am actually studying and understanding everything that was contained in the lecture, I have no need to go over the lecture again that night, if at all....and generally not until right before the test.
When I wasn't using this method, I was struggling to wake up and then stay awake for a full's day worth of classes. Some classes were helpful, some weren't...but in the end I'd be too tired and short on time to effectively review the days material that night. That doesn't even take into account the extra time and energy I now have to do things such as go to the gym, run errands, take naps...etc
None of this would be possible w/o a scribe service and/or mp3's...especially the mp3's bc I know that I have not missed anything said in class because of them.
