Hey ahall,
Thanks for the message and I'm sorry to hear that your final score didn't live up to your, from the sound of it reasonable, expectations. I can tell you from reading various message boards and visiting several chatrooms that last night was rough for a lot of people, so while I'm sure that's little consolation at the moment, know you're far from alone. And please understand that an LSAT score and legitimate shame are entirely, ENTIRELY unrelated! This is a test that humbles everyone who faces it, and while the degree of that may vary, struggling with something that's profoundly difficult is completely normal and nothing to ever feel bad about.
As I read your message I feel like there are two points of discussion raised: (1) what might have happened on the LSAT to cause your score to be a little lower than the range you'd recently achieved; (2) should you retake given the numbers of your target school. Let me try to address both.
The real bummer about the Feb test of course is that it's not released, meaning not only do you not know exactly how you performed in each section and what you got right and wrong, but you don't even know how many questions in total that you missed. So attempting any kind of post-test self-analysis is virtually impossible from a content standpoint. What you can do is consider the overall experience and compare it to recent practice tests, and try to perhaps gauge how you felt as you moved through the Feb LSAT vs how you felt on recent PTs that were both successes and...not successes (I don't want to say "failures" because that's a really foolish way to consider an experience you can/should learn a lot from).
So with that in mind, and taking into account the information below, I'd be curious to hear how you felt it was going section-by-section, moving through the actual test. Was your level of confidence in the answers chosen as high as it was when you scored 150+? Did you find yourself moving at a 150+ type pace while doing RC passages, or setting up and attacking games, or trying to finish LR sections? How about general anxiety: to what extent do you think nervousness might have played a role on the actual LSAT compared to one of many sample practice tests?
Those may seem irrelevant to your second question, but when considering a retake I think it's always important to predict, as best you can anyway, what sort of improvement is probable the next time around.
Your question about admissions odds with a 144/3.34 is also somewhat tough to predict (for me, anyway), partly because every school is a little different in what it values more or less, and partly because there are a lot of other factors that play into an admit decision--personal statement, letters of rec, general/biographical information, etc. Again, hard for me to quantify all of that with much certainty, so it's probably in your best interest to call the school in question and speak to someone in admissions. They'll be happy to answer questions and will do what they can to steer you down an "apply now" or "take it again" path. Truthfully, application numbers are so low the past few years that schools, especially schools with lower-number criteria, are desperate for applicants and have become exceedingly helpful when dealing with prospects. Use that to your advantage. My suspicion is that they may tell you to apply with what you have, and also note that a higher score is always a bonus (for you as well as for them).
Finally, there's a tool released by LSAC (test makers) where you can input your LSAT and GPA numbers and get admissions odds feedback for the majority of North American law schools:
https://officialguide.lsac.org/release/ ... alsat.aspx . I don't know where you're applying, but plug your data into that calculator and see how things look. It should give you a slightly clearer sense of your chances of getting in.
Again, sorry to hear that the numbers released last night weren't quite what you'd hoped they would be, but from the sound of things I think you're still going to be okay.
Keep me posted!
Jon
