bio a level practice questions - where to find??

hi. I do OCR A for bio a level (I also do ocr chem and Edexcel maths and fm) where is a good place to find practice questions? I know pmt has a lot but I was told they are from past papers so surely by doing the pmt questions I am diminishing the usefulness of doing past papers? any advice much appreciated!

Hii I love savemyexams for practice questions, since they make their own questions as well as loadss of past papers. They also have revision notes. But I am not sure if their practice questions are available to people without a subscription.
I also like Cognito and StudyMind for practice questions. Cognito is more basic but StudyMind will give you full on whole papers full of practice questions on specific topics which they have made themselves I think.

thank you! yes save my exams only has limited qs if u don't have a subscription but maybe I will get one. ill check out study mind asw!
