  1. Hi. This website is so useful I have been using it since my AS to revise :). I was wondering if you had any photosynthesis questions…i am getting so confused on light dependent and light independent stages I really would like to practice on some questions!


  2. I could not agree more with people that say teachers are like Gods! You truly are amazing and I would like to thank you ever so much! 😀

    • Well thank-you very much.. what a compliment! remember that it is you that does all the hard work, so you deserve the praise as well you know! I hope you get the grade you’re aiming for when the results come out 😀

  3. Hi mrs miller, love the site n find it realllly usful. jus out of curiosity, are your past question packs a compilation of different exam board’s questions too? Thanks.

    • Hi, These questions are just from OCR. You might be able to get other exam board past papers by going to the exam board website e.g. AQA and searching there. I hope this answers your question. Good Luck!

      • Dear Mrs Miller:

        I would like to make contact with you, I live on Jamaica W. I. If you could send me a contact number or an e-mail address I would appreciate it.


      • Hi, anything I post on here is public, so if you comment with your email address, I will email you directly if that is ok. All comments automatically go to my email before they are made public, so your email address should not be seen either 🙂

  4. Hi, just wanted to say the site is brilliiant. It was a real life saver for AS revision. I found the question booklets so useful! I am planning to continue biology onto A2 and was just wondering if you had question booklets relating to a specific topic for the A2 specification like the ones for AS?

    • Yeah, they are all on here under A2 Biology… thanks for the comment!

  5. You are amazing!

  6. Hiya, I also think that your website is amazing and it helped me so much in getting my A in unit 2 of biology at AS. I was just wondering whether you have question and answers for the first unit of a2 biology, the photsynthesis, communication and homeostatis and excretion modules? Thanks

    • They are all on here in A2 if you scroll down. Thanks for the comment

  7. Hi, Thank you so much ! just wondering do you have any cellular control powerpoints, for all the topics within the unit? Please

  8. WOW! There are some extremely useful questions on here

  9. Beautifully done website, thank you!


  11. This website is amazing THANK YOU SO MUCH, do you happen to know if there’s a chemistry one similar to yours?

    • Hi Lydia, the only chemistry website I know is doc browns chemistry page. You should find it if you google it. Sorry I can’t be more help, and thanks for your comment!
