Preparing (somewhat unsucessfully?) for the AMC

One of the things I really have to catch up with this winter break is preparation for this year's AMCs. Unlike last year, where I took both the A and the B exams (10A and 12B), this year our school is only hosting the B (stupid high school exit exam getting in the way of everything... completely pointless if you ask me >.<), which means I only have one shot to make it to the AIME. Nevertheless, I am fairly confident about the AMC - today I scored 114 (out of 150, 100 and higher qualifies) on a practice test, so I think I'm all set for that. However, for the AIME... let's just say this is looking to be a repeat of last year (5/15, due to 4 rather careless errors) - I scored a miserable 2 on a practice test, again because of carelessness on my part. Granted, I haven't had any practice since this summer, but still... Looks like I've got a lot of work ahead of me... ;)
