“I can take Spanish 3 as a senior,don’t know if they will see it on my transcript if I apply early action though.”
Not on your transcript if you apply early but they will see it in your senior course load, which you will be required to list. If you are deferred or apply RD, they will then see it on your transcript.
Would highly recommend the third year of F/L. Applicants to LSA should ideally have four years. Two is the minimum - necessary but not sufficient. It may keep your app. from getting rejected altogether but you won’t compare well against others with 3 - 4 years, including honors and AP F/L. The suggestion of the do-over starting freshman year is good; another one would be that you simply couldn’t fit everything you wanted to into your schedule, and you had to make some tough choices during junior year, with the plan to make it up during senior. That absolutely was the case for my own kid (who ended up having to get approved for independent study finally!) and it has to be a pretty common problem among kids who are outperforming their peers and befuddling the poor administrator tasked with finalizing the course schedule LOL.
