Use Ultrabeat for your signature patterns & loops. Keep them in Ultrabeat and they're available for you to use regularly. It's (marginally) harder to keep regularly used patterns in MIDI files sicne they don't have the associated kit soudns with them.
The point is that Ultrbeat's sequencer and Logic's arrange window are independent. You can drag sequences from UB to the arrange window if you want to manipulate them but loading in a compelte Ultrabeat set brings with it both drum sounds and patterns.
It's a big topic - probably too big for a forum entry. Talk your teaching staff into buying the following:
