Get your money back from Kaplan, they are crap anyway. If you reeeallly want to know what they were going to teach you, go to Chapters/Indigo/whatever, pick up the Kaplan 2006/7 lsat prep book (about $40 or so) and the Kaplan 180. However I would more strongly recommend the Powerscore bibles (Logical Reasoning Bible and Logic Games Bible). You can't get these in Canadian bookstores. The LGB can be bought off amazon.ca, but the LRB needs to be purchased from the US (amazon.com or the powerscore website). Everyone on this board swears by these books. They have also said that princeton review isn't worth the cash, but I believe there is an lsat reading comp book by Nova that is good. Don't take the Oxford Seminar lsat prep course either. It's crap (I speak from personal experience). If you must take a class, try and see if there is a PowerScore/ Testmasters one available. They will teach you the techniques in the Bibles I believe.
Basically you do not have alot of time to prep for the September test if you have yet to start. If you have not done so already, take an actual lsat prep test (timed) to get a diagnostic score. You can realistically expect to raise this 5-10 points by Sept (depending on how much time you devote to studying and how quickly you catch on to the tricks of the LSAT). My best advice is to buy every actual LSAT available (you can find alot on amazon or in Chapters, anything you can't find you can get from LSAC's website, but you might want to get those orders in quickly to get them in time to be worthwhile) and a couple of prep books that will teach you techniques (preferably the bibles) and just sit and learn techniques and then apply them to test after test. Don't worry about timing the test at first. Start doing some sections untimed. Then do timed sections. A couple of weeks before the test, start doing full timed tests. You will probably need to do 3-4 per week to really build up your stamina. Don't worry about the writing sample at the end of the test. Pick a side, argue for it, but don't forget to argue against the other side aswell. Most law schools will never look at the thing anyway. HTH
