Won’t be able to pass chemistry?

There isn’t anything I am able to comprehend in this class. The professor spends 2 seconds on a subject and goes to another subject and doesn’t teach at all. I went to tutoring and the lady would just stare at me until I came up with the answer but I couldn’t. Just said I’m taking on too much this summer. And didn’t help. I can’t make myself understand a single concept and this is the only class I need to pass my program. I will literally have to work fast food for the rest of my life now just because of this class.
