I can only imagine that you'll manage the foundation (rather than practitioner) level unless you are particularly good at distance learning (I am not). We had a temp who managed to pass it with just a lot of time spent with the Prince2 manual; it's not that difficult. I'm afraid that I've only done the practitioner with a proper 5 day course so can't really help you however I believe that Axelos now "own" the method so perhaps look for a training provider from here:
