Yep, looks like the version he saw on his computer didn't have those scenes or he ignored them because they didn't fit with his preconceptions of the movie.Then you haven't really paid attention watching the episodes. In WNMHGB and "Shoreleave" they establish the young Kirk as a serious student who obviously later in liofe loosens up with more confidence and relaxed disposition. Later in a couple of episodes of TNG it's established that the younger Picard chased skirts and was a bit of a rabble rouser. So what Abrams effectively did was take the younger Picard's personality and graft it onto his alternate universe Jerk, er Kirk.
Roddenberry thought of Picard and Kirk as his own ideal self at different stages of his life. So it isn´t far-fetched that they share the same background.
And Kirk is portrayed as studious and intelligent in the movie.
He knows the definition of xeno-linguistics.
His aptitude tests are off the charts according to Pike.
He graduates in three instead of four years.
He is able to reprogram the Kobayashi Maru test.
He refers to Pike´s dissertation about the Kelvin when they are heading to Vulcan.
Actually, Kirk is portrayed as being so smart that he does not have to study. It's a nice fantasy, one that has caused many a brilliant man (and woman) to fail course after course because they see themselves as too brilliant to deign to do something as undignified as homework.
I teach high school. I see it all the time.
