For modern, my guess would be anything above 97 (thats probably the bare minimum though). Not too sure about EE1, but from what I have noticed, you would probably need 48/50.
Yeah, come to think of it 100 for EX1 sounds about right because so many girls at my school get 48/50. One year a girl got 50/50 at the marking center but her teacher at school took 2 marks off her internal for being very slow in getting work in on time.
