I got a lot of easy A's on my papers by writing about something that acted as an experiment.
This might fall under comparison/contrast
Like I did a paper where I took three dreams of mine. One that was the whole story with a lot of details. One that was details of a portion of the story only (like I forget the rest of the dream, but at one point, I was in this house, standing in a living room, the carpet was blue, there was a bird ornament on the table, there was 7 books sitting on the floor) and then I took a dream where I forgot all the details, but I remembered the main idea (like I was here, then I was there, then this guy was trying to, then I woke up).
Then I took three different dream dictionaries. I had one by Betty Bethards who is a mystic, but Carl Jung was her main inspiration. I went online and found one psychological only and one mystic/superstitious only.
I compared and contrasted all the definitions of my dreams to see if dictionaries were worth a darn.
ANOTHER ONE I DID dream based, was I took the dreams in the Bible that Joseph analyzed (for the pharoah, and for the other guys), and I compared and contrasted Betty Bethards' dream dictionary analysis of the same dreams to Joseph's. It was actually quite funny with Betty Bethards book because one was the guy got hanged, and his image, she said "To lose one's head" or something. That one I did I think I wrote the paper on my lunch break at work (after I had already analyzed the dreams and had notes), and I still got a 100% on it. I'm sure it had many grammatical errors and was poorly written. I probably wrote it no different than the way I type on this forum. But it was for a Religion Class and not English.
