Plot hole: It is never explained to the audience how Ben could fix the "incomplete" essay which would prevent him from graduating at MIT and being eligible for Harvard Med. In fact, Prof. Rosa, who was both the one who provided the initial cheating vote to the non-existent essay and then stripped it away after fighting with Ben, states that he will remedy the essay's deal only if the last trip to Vegas results in sufficient money. Then, Prof. Rosa gets kidnapped by the security guys and is never seen again.

Question: If the 21 game is still played in casinos, there could be hundreds of geniuses who can count and cheat the system as shown in the film. Is this a possibility, or have casinos adopted extra security measures or something?
Answer: Yes, most casinos have now upgraded to the automated card shufflers, which constantly shuffle the cards after each deal, so there is no way that counting cards would be possible.
Answer: Casinos have always looked out for people counting cards, even before the real events that inspired this movie.
