Cells and Immunity

NEW! Download my AQA Topic 2 notes (cells and immunity) for only £3 on my buymeacoffee.com page here.

AQA A-Level biology notes pdf topic 2

Exchange and Transport – Only free for a short while longer!

These A-Level biology revision notes cover the whole of AQA Topic 3 and OCR A Module 3. (Edexcel A do not cover this topic in so much depth but I may make a smaller pack in the future.)

(Note: in the AQA cardiovascular disease notes, the diagram should say “atheroma forming under artery endothelium“)

Key Terms Glossaries

Use these to refer to as you are learning or revising a topic – don’t try to learn them off by heart!

Cells and Organelles

Revision cards about the different cell types and the organelles and structures found within them.

If you notice any spelling mistakes in these please get in touch – I work on my own so I might have missed one here and there.

Please note that these packs don’t necessarily cover a whole topic in the specification and may use information from several topics. The colours may vary slightly depending on what device you are using. Make sure to use a range of resources to revise for your assessments, and do lots of practice questions.

    1. Hi Anna, I’m sure I will do some more notes soon! Unfortunately I think it will be a long time before I get through every topic because I do these in my own time for free so it’s not something I can do quickly. I’m glad you like these ones though, thanks for visiting!

      1. i’m so grateful for these notes. literally saved my ass these past years. <3

    1. Thank you, I’m glad you like them! I have just updated the Molecules in Biology ones to today so make sure to download the latest version – just a couple of minor changes.

      1. It’s just amazing maama…
        I can’t believe this😭🤧💜 really appreciate…
        Btw ma’am can you please tell me is there any books’s notes others than science
        Like math

        We will be really appreciate if you make math’s notes on important topic
        For basics 🤕😞😊💜
        May God bless you

  1. I absolutely love these, i like to look back on them from time to time to help me revise since some of these are what i have already learnt but need to practice more on so i could remember it for next school year, and the ones i didn’t do will help me keep ahead.

    1. Hi, everything I currently have is available here. Working on more currently. Don’t forget to click on the topics page to look through my articles as well.

      1. Hi Anna, I hope to be able to write more notes in the future but I need to start getting a little financial support for the huge amount of time I spend doing it – if you can, support me at https://www.buymeacoffee.com/zhtutorials to help me reach my first goal! I have also written quite a few articles which relate to topic 4 – check out the ‘genes to proteins’ series under the topics tab.

    1. Thanks for your comment. I don’t currently tutor anyone doing the CIE exam board, so I don’t have enough knowledge of the mark schemes etc to do that yet. Maybe one day though 🙂 The content is probably quite similar though so hopefully the existing ones will help with your understanding.

  2. Hi, I’m Anna. Thank you so much for these amazing notes. You are wonderful! God bless you! Have a good day ahead and keep safe!

  3. Hello, I paid £20 today and I would be willing to pay more if you could do complete notes for A Level Biology OCR notes. My daughter loves them 🙂

    1. Thank you for your very generous contribution, it is much appreciated. I think it will be a while until I complete a full set of notes but I will definitely be working on some more soon!

      1. How long would it take for your to do topic 4/5/6 OCR A because I’m gonna fail without your notes 😫

      2. Probably not this year I’m afraid! You definitely don’t need them to pass though – make sure you do lots of past paper questions to get familiar with what the mark schemes are after.

    1. Thanks, I’m glad you like them. I hope to do chemistry as well one day but I need to build up a bit more financial support for the time I spend on it first. More biology ones to come fairly soon though I hope, when I reach my first goal on buymeacoffee.com 🙂

    1. Hi, um yes? The latest topic 4 key terms glossary was uploaded only 3 weeks ago. I do plan to continue making them but it is very time consuming for me to do and I only have my own time during evenings and weekends to do them. That is why I am hoping to reach my first donation goal at buymeacoffee.com/zhtutorials before working on the next ones. Please consider making a small donation if you like the notes and would like to see more.

  4. these are amazing exactly what I needed as my notes werent upto scratch and I needed to revise!!!! Pleaseeee get all of the topics of AQA alevel bio done if possible as the ones right now are really good and would be very helpful if more topics were on thanks

    1. Hi John, glad you like them, definitely planning to do more as support comes in. Follow me on buymeacoffee.com/zhtutorials to keep up to date with what I’m working on!

  5. Thank you so much!!! Your notes are a lifesaver. Can you please do some on biodiversity and classification. 🙏🏻🙏🏻

  6. i love your notes! I am currently doing Edexcel exam board, do you know when more of these notes will be uploaded?

    1. Hi, glad you like them. My next set will be released some time after Easter but probably only AQA and OCR. But then I promise I will work on an Edexcel set. The topics are so mixed up and different compared to the others so I have to do them separately to make full topic packs.

  7. I beg you to come out with all the OCR A topics. Because I’m struggling to find notes that are like these. ( They’re amazing)

  8. would you be able to make revision notes for all topics? I am extremely grateful for the ones you’ve provided us with as they are so helpful with revision. Thank you so much
