This blog was set up to give information and advice to students in my various biology classes a few years ago. But over its existence it has changed markedly and has slowly turned into an open resource for candidates revising for IGCSE Biology exams.  I am almost at the point where the entire specification is covered in some way in the blog, so the best way is to use the “Search PMGBiology” function by entering a key word in the topic you are revising on the home page. Although almost all the posts relate to the EdExcel IGCSE Biology specification, you will have to forgive the occasional blog entries about rackets, real tennis, the Cobblers and my general witterings about life.  I hope you enjoy my posts and find them useful.

This is a personal blog and has no link at all with my employer.  All views expressed are mine alone and do not reflect official school policy.

A small request:

If you do find this blog useful, please leave a reply to say so.  I want the blog to be as interactive as possible, so please do ask questions, suggest good topics for future posts and leave comments/replies as appropriate.  I will do my best to respond to every comment received.

    Hi! I found this website while searching for information related to a specific Syllabus point (4.18B), and I absolutely loved the explanations you gave (particularly on evapotranspiration). Since solidifying that concept, I have used your website for many other syllabus points, and I truly believe that this is one of the best resources out there for IGCSE biology.

    Thank you for creating this website, and please continue doing so in the future! I have sent this website to many friends of mine in Years 9/10/11, and they love using it too!

      Thanks for your kind message. I am really pleased you are finding the website useful for IGCSE Biology revision. I haven’t had time for many new posts in a while but I will write some new stuff in the run up to the summer exams. Keep working hard!

    Hello – thanks so much for this brilliant resource. I was just wondering whether I had the permission copyright-wise from you as the author to make the posts into Quizlet sets to test myself. Thanks again for the time and effort you put into each post.

    Thanks so much for making this, best revision resource I’ve ever found 🙂 I just found this website so I might have missed it, but is there a way to filter by topic or syllabus point? (I’m trying to get most of my notes written over the summer)

    • Paul Gillam

      Thank you for this great feedback. I’m pleased you find the website useful. There isn’t a way to filter but you can use the search functionality – try putting in a key word or if you are doing EdExcel IGCSE, try searching by syllabus point… Good luck!

    Wish I had discovered this website a few month ago for my daughter! Great detail. Paper 2 biology question this week asked why plants can be micro propagated and animals not and my google search brought me here! Please keep this resource going and add in for A level as my daughter will be doing this starting in September! Thank you for being generous with your knowledge.

    Hi Paul, we have come across your Blog and find it most helpful, really clear and thorough. My daughter is studying this syllabus at home – we are looking at Zondle can access the questions
    but can not see the multiple choice part – are you able to send us a link to these?

    Thank you in advance
    best wishes

    I’m going to be taking my IGCSE in Jan so i can undertake my PGCE- any predictions on what might be in the paper would be great ! (but yes, i know, i should learn all of it -just in case)

    • Paul Gillam

      Good luck with the January papers. It is hard to make predictions for a stand alone exam but if you look through sets of past papers, you can see that many topics are repeated from time to time. I hope you find the blog posts useful and enjoy your PGCE. Best job in the world!

    • Paul Gillam

      No worries – I hope you and your students find it useful. I have rather neglected updating it in the past few months but as we approach Easter holidays, that is often my busiest time of year for writing posts…. Let me have any feedback to help me improve it.
