No offense, but why are a number of you STILL worrying about what your parents think? Come on, now, you're all at uni, which means you're all 17 or 18 at the least. That's when you guys should be starting to cut the umbilical cord and taking control of your lives. If you need to take a day off because you can't be bothered travelling four hours to get to a one-hour lecture, just do it without worrying about "parental approval."
Anyway, I also live in the west and need to travel four hours daily (two hours each way). Like TrueTears, I also try to cram all of my tutorials in 1-2 days and end up skipping all of my lectures. I've found that I perform just as well in every unit irrespective of whether I attend the lectures or not (in the Arts faculty anyway). Last year, I managed to cram all of my tutorials into one day (9am-6pm) and I found that it was far too mentally draining, even with a one-hour break in between. I was completely buggered by 4pm and ended up nearly falling asleep a few times in my last tutorial of the day. Two days per week is perfect for me.
After nearly two years of travelling from Werribee to Monash, I've gradually become accustomed to a routine of reading and sleeping on the trains.
