A smart idiot 

One who excells far ahead in school but is rather stupid in the sense that they are close minded and not tolerant of people different than themselves. They often see themselves as better than many other people and judge people solely on their academic achievements and not on their personality or moral values.

The opposite of this is a dumb genius. One who does not do well in school but is very street smart and if he put in effort would do well in school as well.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
