Those flashcards are great to learn the basics... they are pretty lewd too, so if you can find a person that you like, they might be a great ice breaker.. hahaha
emmanuel's is alright... i think the best thing to do is to teach yourself early on how to break down the RSC and UCC rules into elements so that you can understand them... go to your teacher if you have trouble doing this and make sure that you figure out how to do it on your own..
when it comes time for the exam, you'll know exactly how to apply the fact patterns to the each element of the rules to come to legal conclusions.. unfortunately, i really didnt learn how to do this until two weeks before my exam.. fortunately though, the exam was open book/open note.. it turned out the most useful thing ever for me..
