<p>I agree with the advice to check college websites and keep in mind that many colleges have their own FL graduation requirements. My younger son struggled with Latin in high school and in the end decided to do the fourth year even though he’d finished Latin 3 as a sophomore. He’s ended up in IR and is now struggling with Arabic! (He has said his biggest regret with Latin is not having had experience with a spoken language - he felt it put him at a real disadvantage with respect to other students.) </p>
<p>Consider also whether Spanish might be useful in his future life. As an architect I have a surprising amount of contact with Hispanics and wish all the time I’d studied Spanish instead of French and German.</p>
<p>All that said, on balance for your kid, I suspect dropping Spanish will serve him better, at least in the short run.</p>
