Your claim is that their education stopped with West Point. So did Lee's. Except by the definition of education Nytram is using (and I'll let you work that out with him), all of them had to learn how to do this without special education.
Lee was hardly even half-prepared as a "specialized staff officer" by Scott.
And it's worth noting, too, that Lee was an engineering officer, not a combat officer, and that his commands in the Mexican War were as small in scale as those of everyone else. Thus Lee didn't have any more experience than the rest of them, and his failures in Georgia and West Virginia illustrate this.
