I already speak Spanish and I’m going to take the Spanish course. My school offers a Spanish course for non-Spanish speaker and another course for Spanish speakers if I take the Spanish course for non-Spanish speakers even though I know Spanish would it look bad on my college transcript since I was taking a Spanish course for non-Spanish speakers when I knew Spanish?
Yeah probably. Colleges want to see rigor.
If you already speak Spanish, take a different language. Like snow fairy said, colleges want to see rigor, taking a language you already know will not be viewed as rigorous.
And getting a 4 on an AP test for your mother tongue would likely count against you.
1° If you are a heritage speaker who can read and write, whose parents have college degrees… take AP Spanish alongside level 1 of a FOREIGN language freshman year, then continue the foreign language through level 3 or 4 sophomore through senior year.
2° If you speak Spanish but don’t routinely read/write it, take Spanish for Heritage Speakers 1&2 then AP Spanish Language.
3° Taking Spanish for non spanish speakers will be boring and you’re likely to be a problem because everybody but you will be slowly starting learning “hello”, “my name is”, “what’s your name” and you won’t be learning anything, making the others feel terrible or angry at you. And of course it’d automatically make colleges wonder why, with the logical answer being “no work ethics”, which would obviously count against you.
