请问T5对四年外语的要求到底有多严格？我们学校counselor信誓旦旦的说3年就够了。可是大学网站上明明说的是4年啊。

我们是个小私校，对选课种种限制。我们高中前三年一直是spanish。12年级counselor建议不要再选外语了，这样空出时间多选一门 stem 课。她说 T5 三年外语足够了。可是大学网站上，比如P家明明写着

If possible, we expect students will complete the following courses before beginning study at Princeton: 

• Four years of English (including continued practice in writing).

• Four years of mathematics (including calculus for students interested in engineering).

• Four years of one language.

• At least two years of laboratory science (including physics and chemistry for students interested in engineering).

• At least two years of history.

但是又觉得学校的counselor不至于骗我们吧。真是糊涂了，这种大学对外语的要求到底有多严格啊？还有, 这些年限要求都是说的高中吧？娃 middle school 学过两年 spanish不能算数吧？
