I've voted for "hard".
The questions obviously included Mechanics but felt more sophisticated than the past papers I'd done. That being said, apart from the non-uniform rod question, everything felt doable.
Questions like (a) find P AND R were unusual too. Not to mention the Vietnam flashbacks when I saw pt^2+qt+r.
It was a Mechanics paper, but it didn't feel like an Edexcel M2 paper. Hoping its around 56-58 for an A.
