Rather than avoiding them, just approach it logically. Even if you can't come up with a great answer with great reasoning, just write down a possible answer, and SUPPORT it with a few good paragraphs, covering each aspect of the question. Organization and logical support counts for a lot... even if the content isn't stellar. This isn't a literary competition. But I wouldn't skim over them, it'll just make you more nervous knowing that you have to go back to it. At least it would have for me.
