Thanks everyone, I'm going to talk to the instructor today, but yes there's a lot of information which has been superseded as the regs change and the CAA try to deal with Brexit.
The Skyway Code doc is a good one, lots of stuff in there which tbh is a good refresher & summary of many changes (albeit the pun-tastic name makes me cringe).
I'll take a look at the AOPA - was regularly getting mails form them but don't think I was a member.
