In freshman and sophomore year I took Spanish II and III respectively. For my junior year I did not take a foreign language. Now that I am approaching senior year, I’ve been offered the opportunity to take Spanish IV. Will it make a difference whether or not I choose to take Spanish IV in my senior year, or is the damage already done?
For college admissions, you mean? If a college requests 4 years of FL, they won’t care how you got there. More of the challenge will be getting back into the groove after being away from Spanish for a year, but it’s easily done.
Take the class. Most colleges ask for three, prefer four years of a language. Getting to IV will probably give you a pass on the four-year-required thing (since you can’t go any higher).
