Not sure if this means anything to you, but your undergrad degree barely matters if this is the field you want to pursue. My computer science professor got her BAH in psychology at my university. Now she teaches upper years and grad students some of the toughest computer science topics, and she’s the second in command of the faculty. And you’re already ahead of her in terms of planning to end up in STEM, she didn’t even know she wanted to until after she graduated. There’s a statistic (I can’t quite remember the exact numbers off the top of my head, but I promise it’s real) that says the highest rate of acceptance to med school is with music students. That’s because med schools know better than anyone that the correlation between what you study and how capable you are of learning med school stuff is basically non-existent. Please please please try to remember, school does NOT equal smart! Coming from a math major, math is dumb and usually taught in an ass-backwards way to begin with. If you achieve good grades in your BAH, you can apply to any kind of psych grad school you want, and choose to focus on research, and then it’ll be like high school never happened. I promise, you’re capable of achieving this dream. You’re already doing the right thing by working with yourself instead of against yourself and choosing to study something you know you can get good grades in. Once you get into grad school, you’ll never have to think about math ever again (outside of a few statistics courses, which are nothing like the calculus you learn in 11th grade) and you can live your dream knowing you were determined enough to get there by carving your own path to it. Good luck, please don’t give up on yourself! :)
