Rate the following essay on its writing, argument, and language skills:
The Facial Action Coding System, or FACS, could be useful for school purposes, and may help students and teachers tremendously. On the otherhand, however, it is not perfect and may cause more issues than it solves.

For school purposes, the FACS can be used to alter an online course, assessment, or even just a simple knowledge check, using facial expressions to determine if the students are confused, bored, or if they understand it. If they are confused, it may be altered to help them understand whatever it is they're working on. For someone who is bored, it may try to make an online course more interesting to grasp their attention.

However, the FACS is not perfect. It may mistake a facial expression for the wrong emotion. This could result in issues involving altering an online assessment, or course. Some students may feign emotions, and make faces to do the easier course that's meant for students who require additional help. Also, students who take an online course may be confused about something else, not the course they're taking. The FACS will still read that expression as confusion and alter it because of that confusion.

Altogether, I feel that these cons outweigh the pros too much, and I believe that the FACS should not be used for purposes such as an online course or assessment. Too much may go wrong too easily with the use of FACS.
