AS level maths practice book worked solutions

Hi! I’m working through this practice book and I’m stuck on a few, is there anywhere I can find the worked solutions like the ones on PMT for the normal books

I think you'd have to tell people which exam board and which particular book / publisher you're talking about to get more help
Alternatively, why not post a question that you're stuck on here along with your attempt so far, and someone can give you a few suggestions.
