Toughest paper by far. Tougher than the IAL and the Rs etc etc. I dont expect boundaries to shift significantly though.

They have intentionally made the papers tougher, and the boundaries haven't fallen by the same relative amount.

The number need to square so the variance would different from part b or c as the any normal distribution may not independent I think
