Starting A&P school

Hi everyone I’m 22 and I’m starting a&p school next month on the 23rd over at AIM (I’ve read it’s not a good school and it’s expensive) however I’m only paying 3k out of pocket so it’s not bad at all,and it’s the closest school and only school in my state. is there any tips or anything you feel like I should know while in school, and did i make a good decision for my age? I work full time so I’ll be taking night classes, thank you in advanced to anyone that replies to this post l.
