When you’re working your way through the LSAT, it’s easy to get caught up in a difficult question, and the test-makers know it; that is why the questions are not presented in order of difficulty (it is true that the first question on an LR section is generally more straightforward than the last, but there is quite a bit of variety in the middle). Even if the test makers did want to put the questions in order of difficulty, everyone has a different set of strengths and weaknesses.
All of this is to say, the questions that are most challenging for you will show up in random places in a section–so when you encounter one, skip it! The more quickly you skip over any question that even looks like it will be annoying, the better off you will be. It’s also easy to overestimate the amount of time and effort it takes to recognize that a question is challenging. Generally, though, you can tell by reading just the first line or two.
There is no reason to stick with a difficult question when you could be breezing through the more straightforward questions that happen to have been placed later in the section. Take a practice section or two to get used to skipping past initially-confusing questions, and you should notice not only a greater sense of comfort with the test, but a higher score as well!
