For those who are in the 170+ range on LG, how do you know how many inferences to make up front? As JY says, it helps to have made a decent amount but sometimes I spend too long doing that and it hurts me on time and the questions ending up not needing all those inferences.

When I make a mistake on logical reasoning, it seems to have to do with having misread something in the stimulus or answer choice. For example, reading "apples" instead of "some apples". There's a warning this has happened because none of the answer choices seem to make sense. The problem is when I go back to reread the passage and answers, I tend to make the same reading mistake again. However, when I reread the question the next day the mistake tends to be gone. Its almost like I'm temporarily stuck and I need to reboot somehow.

Has anyone experienced this and do you have any advice?

My home environment isn't a reliable place to take the test. I am considering taking at a testing center. Has anyone tried this? Do they provide the computer the test is administered on, or do I need to bring my own?
