Yes. My honors AP English teacher (this is a college course, keep that in mind) asked us to write a paper on Hamlet and his "Tragic Flaw" in the Shakespearean play. The assignment had to be 500 words long, and we had to use a few certain sources. I used all of those sources in a completely bullshit way (referencing them only for short bits just to complete that part of the assignment), and I wrote six hundred or so words on the first few paragraphs, then decided just to quit writing. I know what you're thinking, "wow, you deserved to fail turning in something like that on purpose", and you should be right. But you're not. You're dead wrong. The one thing she takes of points for is the way I wrote it. Specifically, that it was written too intelligently. She said that it would be hard for someone to read it and understand it. I pointed out that it was all grammatically correct, and nothing was wrong in that sense. She agreed but didn't care, insisting that it was important to make it simple for my audience to read. I then pointed out that my "audience" was in fact her, a college english teacher. She (no lie kids) responded with "Well, it was hard for me to read." Bullshit.
HELLO SAT. I got somewhere between a 6-9/12 on the stupid prompt because I wrote it like an AP english paper.
OOOOhhhh That's not the same as being "intelligently written." Economy of words. I've had teachers over the years tell me that I use certain words when others could've been used just fine. It's about being concise and clear as opposed to using wordplay to hammer in whatever point you're trying to make. My teachers that've told me this (and they're not idiots, so it isn't like they're asking me to dumb it down for them) were saying that the best essays can generally be read by anyone and can still convey the point directly (sans the supporting material from the text).
Saw the new Harry Potter. It was a good movie and I was like the 10th person in the theater when I got in, 30 minutes before the movie started. Anyways it was a good movie and the largest cliffhanger in the world. On RST's situation it might have been your vocabulary that was too intelligent for a simple person to understand but your teacher should have been able to understand and seeing that you are in a college level class that it should be OK to write it the way you did.
