GL Maths MC Papers - which practice papers hardest?

[exam2019]

I know of a student on rank 270 who was offered a place on the waiting list this year which was accepted.

Many parents of students with higher ranks just cannot move into the catchment area by January end up not applying so the ranks go a lot further than DAO, HBS or QE. DG

Thanks DG - any idea roughly what score that might be?
If DD can get into the top 650 then she stands a chance... I just suspect that the standard to make that cut will be even higher than usual this year...
