Caleb is probably the least helpful TA I have had at UVa. Grades harshly with little feedback. He is very arrogant. I thought I was a bad writer because of this course, but I haven't received grades like I did from Caleb since. He seems like he is going to be chill and funny, but it is not reflected in your grades. If you are looking to do well in this course, look elsewhere for a TA.
