Should I still keep going to a class I'm failing

So basically I'm taking Spanish for my uni course and I lowky have an F. Like big fat red F there's no way I'm getting outta that cause I missed a test (not like I would have passed it anyway), have pure reds from other graded work and the only thing that's green is my attendance. I've already decided I'm gonna redo the class next fall, so I gen don't see any point in going to the class. I'm just wasting my time. The fact is I'm not good with learning math much less a whole ass language so I knew I was doomed when I saw both math and Spanish on my outline. HOWEVER in math I acc have a C+ like guys if thats not my best score for math then idk what is. I'll probably focus on math so I can at least past the final exam but gen dont have any hope for Spanish. The terrible news is that my Spanish teacher is also my English teacher..
