<p>I don’t think you should give up being a linguistics major just because of some questions. If you couldn’t solve them after years of study, that might be an issue. But right now you haven’t had any training, and the way you think might not be the way the problem intends for you to. </p>
<p>I’m planning on majoring in linguistics or cognitive science also. Those questions were very interesting though. I especially liked the braille one.</p>
