Is it ok to take the 3rd year of a language senior year?

<p>So I've taken spanish 1 and 2 and did not do very well so i am going to take american sign language. I am a junior and at my school we take 2 sets of classes a year, so i can get 2 years done this year and the final done the first semester of senior year. My question is how will colleges count it as the 3rd year if I'm taking it senior year? Thank you so much.</p>
