Should I skip Spanish lll or lV?

<p>I'm a freshman in high school and am currently taking Spanish ll and I want to be able to take both AP Spanish Language and AP Spanish Literature. To be able to take AP Spanish Lang by junior year, I have to skip either Spanish lll or lV. I will probably still study a little of the Spanish class that I'm skipping or take it at a community college but I was just wondering which course is less important or which one you learn less in.</p>
