I think I can get about 4 prep tests to you... have you tried using the LSAT India tests? they are pretty much the same as far as logic goes... here is the link.... take a look at them: http://www.pearsonvueindia.com/lsatindia/official-test-preparation/
LSAC rates the difficulty of every question in the SuperPrep book, so you can look to that book if you want to start putting together a general idea. To my knowledge there are no official difficulty ratings for any other published question.
... them if you purchase their "Official LSAT Superprep" book. That book ... />

Posted this awhile back but
-Diagnostic July 2014: upper 130's
-early Dec 2014: upper 150's/low 160's
-Jan/Feb 2015: mid to high 160's
Still waiting on an official score though. Hoping for at least a 165+!
I think there was a date where the score came out a day later... but it was a one off thing ... I saw it on a chart online which compared the official release date comparisons with the actual release date comparisons... I'll try see if I can look it up.
@alexandra.k.griffiths What is your last official or unofficial test score? Feel free to private message me if you don't want to say on here but depending on where you're at, 3 months is doable.
I've tried to find them online and while I an confirm that Duke is in the top 10 and Michigan is not, I can't find the rest of the info for the official USNWR ranks :/
