Its across a fw different ones. I normally do very well on readingcomp including the newer tests. This past test just slammed me. I got 7 wrong on readingcomp which is the most I have EVER gotten wrong.
I suck at readingcomp as well. But I can personally say that you are 100% Capable of getting your desired score if you dominate the games, get around 80% correct on LR and just slightly bump up that RC score to around -10.
My favourite part of writing the LSAT is no longer dreaming about playing logic games. I'd take a readingcomp on art history any day over one of those dreams!
