I wish i was good at STEM :(

Taking a research based class and can't for the life of me even understand basic probability and graphs. The more someone explains it to me, the more confused i get. The worst part is, i go to a research university as a humanities major who applied test-optional, and everyone in my class just understands how statistics works. i'm going to work really hard because I'm considering going into psychological research, but if I can't grasp even the basics of research methods and data analysis I don't think that's an option for me. I feel so embarassed in class when I don't understand and keep having to ask questions and it bogs the whole class down
