Hello, everyone! Hopefully this is the right place to make a post like this. If not, I apologize.
I am twenty-three years old, and I'm hoping to finally start going to college and then eventually attend a university. My main concern, though, is that I was not a very good student in high school, so I never actually planned on going because I didn't see much of a point in it. Especially since math was my weakest subject. However, I have decided that I'd really like to become a chemical engineer, which I know is a very mathematics heavy career.
So, how plausible is it for someone at my starting point to pull their math level up enough to be successful in a field like that? My plan is to start out at a local community college, while working full-time, and slowly work my way upwards to an acceptable level. I know I'll most likely have to start at pre-algebra. The only reason why I'm asking here first instead of a counselor, which I plan to do as well, is because it feels a little embarrassing for me to even suggest wanting to do anything related to engineering with such poor math skills.
I'm just a little anxious, and I don't want to waste my own time and money on something that's not likely to work out. Thank you in advance, and I'm really sorry if this was a dumb post to make.
I haven't drawn anything in almost over two years. So, it's not the best. Also, I know I didn't include his mask and shoulder armor. Had a hard time getting it to look right. lol
