<p>In my high school, the Mexicans who spoke Spanish for the easy A usually didn’t get anywhere close to an A. At the college level, the native speakers are likely to be more intelligent then a lot of those in high school. But just being a native speaker doesn’t mean you will necessarily know the grammar, how to read/write, etc. Vocabulary / phrases would be the biggest advantage obviously.</p>
<p>Of course those at the college level, especially higher end colleges probably know the grammatical structures, how to read/write…</p>
