Mr. Del, I hope you read this. You are one of the best teachers I have ever had. You were clear, definitely not boring, and your notes were helpful. I appreciate your two trimesters at Granada. You didn't deserve what happened. I wish you good luck

A complicated individual, in regards to his class I suggest a different teacher if possible. If not a lot of extra effort will need to be put in for the tests which will wholly determine grade.
