Sarcasm

I'm not one to judge, but sometimes I can't read what people are saying online, especially when it comes to sarcasm. Out of panic I emailed my professor when I realized the date for our final was Friday. We usually meet for lecture Tuesdays and Thursdays so I figured our exam would fall on one of those days.

Here's what I emailed:

Hi Professor _________,

I was double checking EEE and it said our final is on Friday, March 19th at 10:30-12:30 pm. Friday, not Thursday. I was wondering if that was a mistake or if the date is right since our lectures are usually Tuesdays and Thursdays.

Sincerely,
Anne

Here's what my professor wrote:

Anne,

Way to stay on top of things. Not only has it been posted on the website since before the quarter began as well as on WebSoc much longer, the first slide in the last 6 lectures reminded you.

--Dr. ___________

That was total sarcasm right? Or am I wrong? If it was truly sarcasm, this gives me more of a reason to despise this class.
