I agree, go for it!! I teach at a college and some of my students have poor social skills, bad grammar, improper punctuation, etc. but they are learning these things while in college. Schools often have resources for these things, too. You could join a club to work on interacting with your peers or go to its writing center to help with grammar/punctuation. There are also math tutors to get you through required classes. Professors are often very willing to help, too. I teach psychology, but don't mind helping my students with their algebra or pre-calculus during office hours. You can do it!!
