This person was another one brainwashed by Scabs for America to think she was better than those stupid teachers who went through traditional education programs because their low SAT scores didn't qualify them for anything else in college. She was soon to find out she didn't know shit when she actually got thrown into a teaching job.
Hell, if you manage to avoid a batshit crazy principal and survive to even have a career in this field, you will find you NEVER become perfect at teaching; teaching, after all, is a lifelong skill. It's just that the longer you are in it, the better you get at it.
Just like any other job.
It's not something you are "born with," contrary to Scabs for America propaganda.
