First, don't mind all the sarcasm/ridicule... unfortunately it's a mainstay here on TLS. Some do mean well (despite their bluntness), others are just assholes... in any case, take it with a grain of salt.
But more importantly, please do not give up your UCLA dream! With that GPA, and with a certain amount of intelligence (which it seems, despite all the sarcasm, that you definitely do have), you are very much capable of attending a school in that range, maybe even higher.
I'll have to agree, though, that taking the test in February will not give you enough time to prepare. To be honest, I thought the same thing when I started - "I'm relatively smart, so I probably don't need as much time as everyone says." But please believe me: to master the skills necessary for logic games and to gain instinct about the LR/RC sections, there is absolutely nothing better than repeated exposure. And I really believe that it would be a waste for someone like yourself to attend a school ranked *that* much lower for the sake of getting there a year earlier.
Also, you mentioned that you studied on and off, but my question is: how did you study? I know you said you did 2-3 practice tests, but what kind of preparation had you done before that? If you haven't done it yet, you absolutely MUST do the Logic Games Bible (by Powerscore). Logic games are definitely the easiest to improve on, and It's been said that with sufficient practice (and a reasonable amount of intelligence, which again, I think you have), you should be able to do logical reasoning with 0-2 mistakes. In other words, if you're still making a lot of mistakes in this section, then please do not take the test yet!
Also, most recommend their Logical Reasoning Bible as well. I'd say it's worth going through once, but more importantly, you need to see a lot of these questions before you really start to gain an "instinct" for them. But once you see enough of them, you really will start to know instinctively which types of answers will be correct and which you can rule out immediately.
Finally, Powerscore also makes a Reading Comp Bible, but the verdict is still out on just how helpful that one is. One thing I would definitely recommend though, would be to check out the suggested study schedules on the LSAT Blog (lsatblog.blogspot.com). He has lots of other helpful articles, but the study schedules really do lay it out well.
Oh, and also, take the most recent tests you possibly can. The most recent ones (after 50) tend to be harder, and especially in the late 50's/early 60's there are some new question types and twists on old questions. If you're looking for extra logic games practice, then the earliest tests (1-20, even up to the mid to late 20's) have some pretty hard ones, but also contain some game types that are no longer in use (still, they're good practice)... the middle ones (30's and 40's) are too easy, but as long as you know that, they're also good for extra practice.
But anyway, now that I'm done re-typing all the TLS collective wisdom on LSAT preparation, I think I'll end my short novel here (before I'm late to work!)... but I wish you luck!
