You could try using 'In Class' or go for the big guns with 'Pocket Informant HD'.
Teacherpal is good for grades.
Let us know how you get on.
I use Pocket Informant HD - combined with BusyCal on my MacBook Pro, I can have unlimited calendars to create various levels of a timetable. All calendars can have different colours - makes it visual quick and easy to view. Interacts easily with iCal on my MacBook and my iPhone - so everything is seamless.
Have also seen, but not used:
- My Timetable (http://itunes.apple.com/au/app/my-timetable/id300573431?mt=8) - $0.99
- Timetable HD 2 (http://itunes.apple.com/us/app/timetable-hd-2/id438103716?mt=8&...) - $0.99
This is a bit late ... only just joined S2L .....
See the screenshot off my iPad for some possibilities.
I suspect, though, that your best solution would be a free Evernote account
A final suggestion is Google Drive ... which is really a rebranded Google Docs ... at the moment Google's iPad gDrive App is not ready ... but Google Drive can be accessed on iPad via Goodreader
I'd be interested to know what you choose.
Im very keen to make an Easy Planning app as the 3rd addition to my Easy Assessment and Easy Portfolio app range. The app would scale back some of the features from the expensive planning apps that I dont think users need and focus on the most useful aspects.
