id say that you should be fine with 70%. During my mod 1 with BGS I was failing tests by a greater margain that that before I went on the course. Even during the brush up on the second week I was failing a lot of the in class tests we were doing. However through a lot of hard work I got it together over the weekend before the exams and passed the lot first time. Just be prepared to put some hours in when you are there, it aint no holiday, especially the met feedback from Ken (u'll see what I mean when you get there)
