No, I don't know of one for those subjects although Airquiz.com is good for the fixed wing stuff.
This book has helicopter specific questions and personally I preferred it over the infamous PPL Confuser. From what I remember, I never found any practice papers for Flight Planning paper and I scraped a pass by winging it with common sense. If you do that paper last, the general knowledge you'll have picked up from your flying should get you through.
