A level math old spec vs new spec

I'm doing the edexcel (2017) math but there's only one past paper unlocked so have been doing the older ones (2008) instead. Noticed a lot of topics that I'm sure I never learnt for my spec.

Centre of mass
Probability function
Dot Product
Regressiion model m=a+bv

Can anyone confirm whether these are not in the new spec? I have checked the new spec but couldn't find any mention of them, just checking here, don't want to get slammed by a question like that in the exam :smile:

Regression lines are in one of the statistics books, but it’s not a major topic. And the other topics are part of further maths so don’t worry about them! I’ve been using old spec edexcel maths papers for mock revision and they seem to be working - the way I’m looking at it is maths is maths!
