Oh, and I use iCal to keep track of all of my due dates for assignments and exam dates.
YES! This is synced with my MBP and iPad and it works wonders. If you use iCloud, that as well works fabulous with the newest iPad, but I've heard that iCloud isn't all that great with the earlier versions of iPad's. With iCloud, my pages/word documents sync up as soon as I open them with either device. I also have pageburst (not so great, but is free with my textbooks), which works as well as it can.
However, ALWAYS back up your hard drive with Time Machine or a USB. You will be lost if all your stuff is gone forever.
For notes, if you have the newest software, Mountain Lion (may be on Lion also?), there is an app already on it called Notes, which is basically a word document that looks like a memo pad.
For powerpoint notes, when you open the powerpoint you want to take notes on, leave it how it is (not playing), and at the bottom, there is a white box for each slide, in which you can type things into and powerpoint will save those notes along with the powerpoint.
One last apps that can be used for school is Reminders, which is basically a different type of planner with alarms and such that pop up.
