Should I do mock? reading, written, recent

Dapper425

I've done the three written exams and the two sample exams (done okay on all). Do you think its worth doing the free mock exam? I have plenty of other stuff to study, which I plan to do in a state of sustained panic. From reading the recent posts here, it sounds like the exam might be coming up soon and I might have to make some choices.

Think its worth the time?
