I'm thinking 90-94
Lost definite 3 marks so far and cannot see where else would lose marks. If on average lose 1 or 2 marks for each 6 marker, then quite comfortably sitting on 94. Can't really make silly mistakes due to lack of calculation questions... but would never know. If 15 is B, then got 14/15 for mc definitely.
two marks down on the kepler's law question (idiot!), maybe one down on each 6 marker, at least 13/15 for mc (15 if 5 was c and 15 was d, but you never know!), so i reckon around 92-94? that sounds about right. that should scale to about 95-96 shouldnt it? certainly hope so.
