"He could have very easily come to one of his counselors and asked for help"
Guidance counselors are the biggest wast in the school systems.
Either you are Ivy League material and you are smart enough to deal with the rest of the stuff, or they say you should consider vocational training.
I remember having to show my guidance counselor how I can make my schedule work. Because she just couldn't do it herself.
So if he went for help what are they going do? Not change his grade, at best you can form a relationship, so she may leave with the computer logged in where you change the grade there.
