lol have the same problem with my latin class
started freshman year and didn't do shit. thought latin was the most useless and complicated shit. now in my junior year (most important years for college app) i started putting some effort into studying and its actually gotten a lot easier, though i am still struggling.
point being, i don't think its that hard to learn any language, given you put a little time into it, and spanish is probably one of those language thats worth learning. Its an investment that will pay itself off. And you should just ask your teacher for the answer key
