1. Register early and then check the classes about two weeks before school starts to see if there are any openings. The add culture at the school is like playing the lottery, a lot of professors are strict about keeping their classroom numbers under a certain amount.
2. Get a parking pass and be prepared to spend at least an hour trying to find parking in the first three weeks of a new semester. It usually starts to level out around the third week, with either people dropping classes or switching their schedules around. If you live in the valley, I recommend instead of driving just using the bus, the orange line stops just outside of the school.
3. If taking a music class, it should be noted that the music center is located on the top of a hill served by about 8-9 flights of stairs. When Woodland Hills hits 107 in the summer time those stairs become your worst enemy. I have seen healthy, 19 year old kids almost pass out on them. If you drive, you can just simply drive your car up there to the music center, but it you don't, well the only option are those stairs.
4. It's a non-smoking campus and they are very serious about it.
