I would give the grammer and sentence structure an 80%; but the continuity and writing style and knowledge of material would be a 25%.
The essay is bumpy and reads like parts of it are copied from sources. It contradicts itself and lacks a clear definition of the main topic. I would give the essay back to you and ask you to re-write it.
But I am not a teacher, so you lucked out.
No, I didn't copy anything from anywhere. Screw you if you say that.
