I was just like her as a teenager. Of course, I was taught more working for McDonald’s and Subway than at school. Most of my homework was mind numbing and repetitive. on the other hand, I was an assistant manager by the time I was 18. Most homework serves little to no purpose besides repetition. If a student can pass a test on the subject, that is the true measure of their knowledge of the subject.
Fast Food such as McDonald’s and Subway is all about repetition. Even for a manager...
At any rate, at that age education is more important than experience. Once over 30 I believe it reveres. Probably because most people have been out of school for a while at this point. Thus, what is important is what have you been doing since. The only time education applies after 30 is when you have two equal candidates applying for a position. Which by the way is very rare. Most of the time WHO and WHAT you know is what will get you a job. That has been my experience.
