  1. Your notes are amazing, though I wonder if there’s note for syllabus 2019. Please tell me if there is and thank you so much for those notes.

    1. Thank you so much for your kind words!! I’m trying my best to get them out before my term starts, but they’re taking longer than I’d anticipated! I am so sorry for the inconvenience!

    1. Nope, these notes are comprehensive, however, they are tailored to the previous Coordinated Sciences syllabus. I am currently working on getting the updated notes out as soon as possible. I apologise for the delay!


        1. Hey, I’m trying to complete the notes as fast as I can, but writing up two years’ worth of notes while juggling my other commitments as a student has severely slowed me down. I apologise for the delay!


  2. theres a new 0654 syllabus some topics or explanations are not there
    there are only 8 chapters in physics in the new syllabus (0654) in this website there is 15 chapters for physics


    1. Yup! I am currently working on the new notes. I apologise for the delay! If you have any other doubts, please do not hesitate to reach out 🙂


  3. will you update these notes if there is new topics that are required to learn in the updated syllabus?
    if you all are the updated syllabus 2019 have added new topics


    1. Unfortunately, none of us has taken that subject so we don’t have the required experience to upload the relevant notes. I’ll post an announcement if we manage to work around that, however! 🙂


  4. Hey IGCSE Aid, I just wanted to point a few things out about the biology section. I have been using your site for the past few months now. Recently I have been studying about inheritance. I have gone through the chapter on this site but have found a few things missing from it. E.g. Mendel’s law, sex-linkage, rhesus factor, blood group phenotype etc. I hope you guys would look into this and add more info. Thank you for taking your time.

    – Shyella


    1. Thank you for your question! I apologise for the late reply, and I hope I got back to you in time!
      I’d like to start off by saying that the aim of IGCSE AID is purely for revision, and so our notes our condensed to contain exactly what you need to know and understand in order to gain an A* for your IGCSE exams in the subjects we provide notes for – nothing more or nothing less. The notes for Coordinated Science are based off of the 2017-18 Coordinated Sciences (Double Award) syllabus on the CIE website (, and the above listed knowledge is not necessary.
      We actually use the concept of Mendel’s law in B9.3 – Monohybrid Inheritance, but the syllabus does not deem it necessary to know the name of the law or to define it, you only need to understand and use the concept. Sex-linkage and the rhesus factor are unnecessary knowledge at the IGCSE Coordinated Sciences level – I only learnt all of that in my A levels. We actually mention blood group phenotypes as an example of discontinuous variation in B9.4 – Variation and Selection, however, the knowledge of exactly how those phenotypes arise is unnecessary – all that needs to be understood at this level is that the different blood group phenotypes are discrete and separate, and so it is an example of discontinuous variation.

      I seriously commend you for knowing all of this at the IGCSE level, but as it is not necessary knowledge, we did not include it in our notes 🙂
      We hope this cleared your doubt!


  5. Thank you so much guys for taking your precious time to write these notes, im writing my final exam oct/November and I’ve been using these notes. GOD BLESS

  6. Thank you so much for sharing your notes, I am currently using the IGCSE coordinated science ones for my October/November exams and they are helping me so much. You explain everything in such a fun interesting yet detailed way 🙂


    1. Thank you so much for your kind comment! I can not express how awesome it is that our hard work is paying off, and that it’s proving to be helpful to you! I love getting comments like this 😀
      A word of caution, though, our notes aren’t quite perfect yet – there may be a few typos or minor mistakes in explanations, because I haven’t had a chance to finish proofreading these notes yet. If you find any mistakes, please don’t hesitate to point them out.
      Good luck for your exams!


  7. Thanks, really:) You did a great job in finishing those off by the end of April. I have my paper 6 in two days, and I feel confident because of your notes. They are a big help. Appreciating it.
    p.s. loves:)

    1. Thank you so much!!! I’m ecstatic that we managed to finish them in time too, but I am sooo happy that these notes have been helpful for you!!!
      Good luck for your paper! I’m sure you’ll do great 🙂


        1. I’m afraid I can’t promise anything – I’m moving house at the end of this month, which has really cut down on the amount of time I can dedicate to writing notes, but I’ll try my best! 🙂


    1. Hi Tara,
      the topics in grey colour are the chapters we’ve finished uploading notes for, so you can click on them to view them. The ones in black have yet to be completed so you can’t view them. We intend to finish all notes by March. Hope it won’t be too much of a inconvenience!


  8. the notes you have given are really brilliant, I take the same subjects as you, really helpful these notes( the once I have done), I think these are even better than Znotes

    1. I’m really sorry about that, but unfortunately we’re all in the middle of our A level exams, so we’ve had to hit the pause button on our progress with making notes. Some of those links don’t load pages because we haven’t made them yet, not because of any faults with the actual links. I hope this won’t be too much of an inconvenience!
