Someone with the Heart of a Poet, Soul of a Critic. We suspend our belief in movie theatres only because we, as an audience, do not have all the facts. Watching military counsel meetings, the crew's soul searching, and some redshirt #2 whining would have made the movie drag on and On And ON AND ...
Knock that chimp off your shoulders and get into the facts as the Director & Writers laid them out on the screen. Art is Beauty; no ugly facts here; remember to pick your brains up on your way out (use a claimcheck, or claim someone else's with a large enough tip). Reflect on these facts later and IMAGINE why things unfolded as they did (Transporter Scrambling Fields, Pike has huge respect for Kirk, Sr., all Starfleet cadets KNEW of Kirk's antics & field-of-study & willingness to approach problems in a way they respected)
Kirk didn't technically cheat. Kirk failed the test 3 times, and the first, second & third score alone would have sufficed for graduation otherwise there would never have been a fourth test. You just don't tie up a simulator and fellow cadets' time on a moronic captain wannabe. Even if he FLUNKed the fourth test, his median grade must have been high enough to justify his captaincy.
