I started timing too late into my preparation, I should of done the gradual approach... I was untimed all the time and then, bam! timed... My score was improving... then it leveled off at 154 or so...
I think I will still take the June LSAT for experience sake, worse comes to worse I'll cancel, and take the classes... suggestions for classes? Powerscore?
I would try to totally forget about what your scores were untimed. They're useless to you and may only give you a unreachable goal. Just because you can accomplish a certain score untimed, doesn't necessarily mean you can get to that score by practicing enough timing.
If you're just looking for the experience, then don't take the real LSAT. Go into Kaplan for a free diagnostic test. They'll proctor it for you as if it was real. Because if you take the LSAT, "worse comes to worst" you'll more than likely fret over cancelling or not cancelling becuase you can't truly know how well you did until you get your score 3 weeks later. In other words, based on how confident you sound now, I predict you'll end up cancelling if you take the LSAT in June. So I wouldn't bother if you feel that unsettled.
I would absolutely take a class if you can. I took Kaplan, which gave me 6 proctored exams, access to hundreds of other exams, textbooks, software, and all the help I wanted in the center. It was 1100 bucks I think, but they have a money back guarantee if you're unsatisfied. And if you "throw" it in with all the money law school costs, it's a drop in the bucket. Plus, a better score on your LSAT thanks to a class can mean a better school and/or more scholarship money.
And GO EASY ON YOURSELF! 154 is a good score for plenty of law schools.
