Here are a few screenshots of errors I found. I’ve highlighted the errors on the screenshots.
This Yahoo article has an awkward sentence. It can easily be fixed by inserting a comma right after the word specifically.
This assignment sheet has a number of errors (I chose to ignore the PM one). The number one should be written out, as numbers up to nine are written out. The word the needs to be inserted before exam.
This class syllabus has a really easy fix: taking out the word exam and perhaps putting a comma after the word choice.
