Enjoy your summer holidays!

Hello guys!
This post is just to tell you that, as you know, I had a car accident last Sunday so I couldn't work last week.
I had told you to have a final exam in order to give you an extra chance to pass or improve your grades, but finally I had estimated an average with your previous marks, It's not really important because I'm continuously doing an ongoing assesment of your progress, so I can be fair enough... I hope you don't feel disappointed.
It has been a pleasure teaching you guys!
Enjoy your summer holidays!!
