I was being a tad facetious with that first part. I believe it would lead to a call with the instructor, or more serious intervention. Which was why I made the next post, about how it will be perceived by other students.Yes, but we are talking about a 9 year old.
There are, however, 9 year olds that can do that. That somehow miraculously have the drive to stay in a corner and work on their own thing. They're not very common, I've met 2 that have had that ability towards any subject, but it's possible.
Unless you meant the part about the setbacks. At which point, my only response is that 9 years old is more than old enough to learn that not everything will go how you want, even if you work really hard, and sometimes you just have to learn to accept that and pivot.
