Well you don't have classes on the Saturday and Sunday, but you will be cathing up on the work from Wednesday! I took the Saturday night of with most of the others, but in all honestly you will be working over the weekend on pratice papers and feedback questions.
There is no way you could do all the work they give you and have the weekend off...
I was working most nights till gone 12pm.. But for the 2 weeks it's well worth the effort.
