    Last years was 65 for 90 UMS, and most people I've spoken to said this was harder. So is it really too optimistic to think it's 64 for 90ums?

    Anything is possible. Having seen the paper as a neutral bystander, I doubt it'll drop to 64, it wasn't that difficult.*

    Looks very similar to June 2014 difficulty wise, I think the realistic guess would be 65/66 for A*. But like I said, anything can happen.*
