All you can do is apply at this point. No one here can help you or tell you whether you’ll get in. But you should think about taking the subject test in one of your languages to help your applications at your safety schools.
I’m sorry your guidance counselor did not advise you better. The high school graduation requirements are the bare minimum in every state. Most colleges require more.
Are there any colleges near you? If you’re fluent in 3 languages, you could dual enroll in one course in the winter session and one in the spring. It probably won’t help for ED, but should for RD, especially if you can place out of the 1st level. If you can take level 2 and level 3, that would count as 3 years of language.
From one of your other threads it looks like you’re a low income student. If you decide to try the subject tests, ask your GC if you can get fee waivers.
I know you’re nervous about lots of things, OP, but your comment was you’re “trying to make up” via the online. The awareness of the expectations tippy top’s have should have come sooner. Not be now looking for work arounds.
What you need to do now is take a breath, let it be, hope for the best. And as we advise all kids, move onto the set of matches and safeties, in case.
The best thing you could do at this point is sign up for SAT2 in some of the languages you are fluent in and send an email to admissions that you will be taking these tests to establish your foreign language competency. Perhaps that would be enough to get a deferral to RD. If you took all rigorous classes instead of FL I think you still have a chance but probably not if you were taking things like study hall and non-rigorous fun electives.
Since you are already applying, it is too late to do AP. You can’t take it until May and the scores won’t be available until summer. SAT subject test or CLEP may be possibilities, though.
How did you become fluent in three languages? If you speak another language at home or if you lived in an another country for an extended period of time then writing persuasively about these experiences may work for some schools (primarily small schools, not necessarily the big state schools that need to crunch through thousands of applications checking off boxes).
The issue, for now, is Columbia. The sequence of FL should take one to reading/writing at more complex level, exposure to the literature and cultures. Even kids with native proficiency are expected to take FL.
You need to prove that you’re fluent in three languages.
One year online is of zero relevance and won’t help you, but if you do have fluency (including cultural literacy, not just “ability to speak/understand when someone speaks”) you need proof through external validation such as testing.
