The ideal foreign language situation should be taking the same FL all four years of high school. Is there a reason you aren’t doing this? Some colleges may require less, but all will welcome/encourage more.
You should not take a math early so that you can take it a second time, in anticipation of possibly failing it. Taking calculus before graduation is a reasonable goal. Some kids take it earlier, but do not push yourself unnecessarily to do so. Create a solid math path so that you will succeed in college, too.
As a freshman, you should plan to take a full year of math, the same foreign language, English, social studies, and science every year. Challenge yourself with rigor by taking honors or AP classes, but don’t overwhelm yourself. Every class doesn’t need to be an AP. Schools like to see rigor, but they also like to see mastery/achievement, so create a schedule that includes the 5 core courses in a way that is manageable to you.
Edit: if foreign language is a passion and you can fit 2/year and do each well, that’s fine. But don’t choose that route in high school if it means sacrificing another core or if it means disrupting a traditional language path. You will have time in college to explore other languages. You could even be a language major and pursue med school, as long as you complete pre-med courses. Medical schools like to see a diversity of academic backgrounds and language acquisition is something that could be attractive to them.
