I just scored a 175 on PT158.

I saw the post about this new feature and wanted to test it out. I feel pretty good about my LSAT progress so far, I have been working at it for a month or so and this is my fourth or fifth PrepTest I think. The main question/advice I am looking for is how to get past those level 5 difficulty questions? No matter how hard I try, they seem to be guaranteed wrong when I complete the test. Not struggling too much with the other difficulties though.
