I thought these were two interesting links about standardized testing. They may not specifically be about the LSAT, but they do offer some insight about the pitfalls of this type of testing. I think the LSAT (and as a matter of fact all standardized admissions test) should be done away with. I recognize the need for an equal scoring system, but I would imagine every year students are denied from schools because they didn't perform well enough on a test, when in reality could be the best and brightest students in a field and their class. I don't know what the solution should be, maybe less weight for the LSAT in the admissions process, maybe admissions officer do more research about an applicants school/major, perhaps more schools conduct rounds of interviews with applicants? All of these of course take more resources that may not be available to all schools, but I think a new system is needed. What do the might fine minds of 7 sage thing?
I think the reason he says to get a classic analog watch is because you can't go wrong with it. The classic casio one he says to get is cheap and durable. The LSAT watches I guess are poorly made and, there's always a possibility your test proctor won't let you use the watch. I would say your safest best is to get a simple analog watch that has a rotating face. This will ensure that you are in the clear and won't have to worry about any stipulations in the rules.
