I’m a new guy just joined thank you for putting this together. I went the automotive route in high school after I taking an electronics and computer tech classes. Turns out spending 12 hrs a day bending over cars is hard on the body and after back surgery need to do something less physically demanding. So I’m back hopefully doing IT school after getting FAFSA results back. And following a path in IT and continuing to learnComment
