LSAC's delay in scoring the tests (a few weeks) doesn't bother me so much. AAMC's delay in scoring the MCAT does. Any other computer test (the GMAT, the GRE, the DAT, etc.) pops up a score as soon as you're done. Now, for the GMAT and GRE, the essays aren't graded yet, but who cares? They give you the numbers for the multiple-choice sections, anyway, and you get a letter or an e-mail a few weeks later with your essay grade. But even though AAMC could do precisely that with the MCAT, they choose not to, and they wait about a month until your essay is scored before sending your multiple-choice scores. Why? Why the heck do they have to do that? It's not like they don't know what your score is already. It's not as though your score is going to change over the next month as they score the essay. If there is a reason for them to do this (and I can imagine a few, but they're more horrifying than sensible, really), I've never heard it.
So yeah, I don't really mind the LSAT taking a few weeks. The security regulations (no water?) are a little ridiculous, but then again, so are people's efforts to cheat on these tests, so I guess they're there for a reason. At least LSAC isn't obsessed with test secrecy to an unreasonable degree, which some other tests are. If you're studying for the LSAT, you have ~60 released tests to play with. If you're studying for the MCAT, you have 8, and a few of those are sketchy anyway. If you're studying for something more obscure, such as the GRE Physics Subject Test, you have 4. For the SAT Physics Subject Test, you have 1. Seriously.
Thus, while we may have some complaints about LSAC, they do a much better job than most test-making companies.
Or it could be like the Fundamentals of Engineering exam. Eight hour test, can't even bring your own pencils for it, and they take up to twelve weeks to get your score for what is a pass/fail test. Although they can get out in less than twelve weeks, as my bf just got his results and he took it in late October.
Personally, I was pleasantly surprised to get my score early back in June. I hadn't found TLS yet and didn't know they usually released them early.
