Top Law Schools

Well here I am 10 days out from what I'd hoped would be a coronation of hard work this past month doing LSAT prep. Just came down with a wicked flu and needless to say I'm really worried about coming into the test and performing sub-optimally because my prep has been railroaded entirely.

I don't have any immediate need for my score (at least 2 years away from making a commitment to law), but am concerned about the LSAC policy for being absent.
My GPA, alma mater, and cocurricular involvements all lend themselves well to a competitive HYS applicant, as long as I keep myself in the upper percentiles of the LSAT.
My concern, therefor, is whether or not these extremely elite schools take a more stern approach when they see an "absent" on someone's LSAT stats, with the reasoning that they already have ample talent to fill seats and don't need to cater to folks who look flaky on paper.
Will I throw myself on a funeral pyre if I can't make HYS? No, but a chance at these 3 schools is indeed a motivating factor in my preparation to achieve a top score compared to something in the 160s that will get me into all the other places I'd gratefully attend.

Thanks in advance for your replies and best of luck to my fellow test takers this coming week!

If you're still sick on test day, I think its definitely better to postpone the test and just write an addendum for the absence.

You should be fine in 10 days but an absence won't kill you or really hurt you in any way. What will kill you (at HYS) is a poor LSAT and retake. I would see how you feel closer to the test and go from there. If HYS is all you want and you don't feel prepared, just don't show up.
