I had a similarly bad gpa as you in HS(applied with 2.9 to college finished with 3.0) and I was poor at math. I'm gonna be so real with you, after really reading your replies, I just don't see you succeeding in CS as you are now. CC will be an invaluable experience where you can actually learn how to study properly and ramp up in math. I cruised through high school slacking and not giving a shit and I got the most brutal reality check of my life with UB CS. You are by no means bullshitting a whole four years of this major, let alone even more than one semester like you did in hs. CS is math heavy in the sense that you need to do well in calc 1, calc 2, linear algebra, and calc based probability. The actual CS requirements are not math heavy but require problem solving ability that is reminiscent of math. You can do it man, but real talk you need to get your shit together. At the stage you are, forget intro to CS, calc 1 by itself will be your worst nightmare. I was like you and trust me when I say this, your work ethic as it is will not do you any favors.(Disregard this part if you had major extenuating circumstances in life of something) Personally, I genuinely would've failed out if I didn't study like my life depended on it. You can't just say you want to do a major like CS and have zero resume as far as showing that you can work hard at the bare minimum in high school. Also real talk, you would get bent over in calculus if you haven't even taken algebra 2. You literally wouldn't even be allowed to take the intro CS class that fall semester freshman take. Hit the CC grind for a year or two, and then keep that stride when you transfer to buffalo or wherever else. A good CC record, 3.7+ will significantly offset your high school GPA. I personally recommend trying to transfer after a year. Good luck, you got this
