Do you circle your answer key OR in the test book?

PT 60's have hit me like a truck. With LSAT coming in less than 2 weeks, I am bombing these new test because of the LR.

I don't know why but I do better in the sections the grader deems "harder, and worse in the ones that are considered "easier."

I don't know what to do. I think I am screwed.

Are there any tricks to comprehend sentences with a double negation to makes them easier to understand?

I missed this question because I was confused by phrase "economy of expression." I was not sure what that meant exactly, and after listening to JY apparently it means something similar to "efficiency of expression."

I missed this one because I thought the stim meant price ceilings, not quantity ceilings, which I didn't even know existed.

This question is confusing, because even though consuming lobsters with gill disease is harmful to humans, as the argument states lobsters do not live long enough to contract the disease. So (E) does not weaken the argument, because the lobsters humans consume did not contract the disease according to the argument.

I think (D) is the better answer. I understand LSAT doesn't want you to attack the premise or conclusion directly, but the fact that it is possible that lobsters have gill disease but it is undetectable seems like a greater threat to the argument.
