Some of the hardest questions in IGCSE Biology are the 6 marker questions and the paper nearly always finishes with one which is more than often about carrying out an experiment. As there is no coursework for this course they must make sure they test you on your experimental knowledge throughout the paper.
If you can master these questions you are giving yourself a good chance of achieving a top grade.
In my new revision resource I have written 10 original example 6 marker questions followed by a mark scheme for each one. You can download it here:
Note carefully how many of the answers are looking for the same things, especially in the practical questions. The key is to think about the variables.
Remember that the aspect the scientist is altering is the independent variable. Whatever they measure or record in the experiment is the dependent variable and all other variables in the experiment must be controlled. If you explain how to vary the independent variable, how specifically to measure the dependent variable and how to control the other variables then you should do well.
I am pleased to announce that I have now completed a PowerPoint for every topic in the Edexcel IGCSE Biology Course. They can be conveniently downloaded in one file containing over 750 original slides.

Over the next few months I will be checking the IGCSE pages and updating video links. I will then begin work on the new linear A Level for 2015.
Any feedback or requests for new resources please email me
I have been meaning to write this post for a while in order to let you know what the plans are going forward for mrexham.com, and this week seemed like as good a time as any with the GCSE results coming out and a new academic year starting.
Firstly I would like to thank everyone who has used the website in the last year, I have received some great emails and tweets and I am really glad that it’s been useful to so many people. I’ve now decided to take mrexham.com in a few different directions. Firstly I am making some of my key resources, which take the most time and effort to make, available to purchase through sellfy.com. This has meant spending more time on these resources to make them as clear and informative as possible, and it has also given me the impetus to make more of them! There will soon be a PowerPoint for each section of the IGCSE course along with revision quizzes.
I will continue to make free resources as well, including Quizlets, revision sheets, YouTube dissections, practical demonstrations, worksheets and I also intend to write Socrative quizzes for teachers.
Given that there will be a new A-Level starting in 2015 (read the Ofqual announcement here) I will no longer be adding to the current A-Level pages and resources. Instead I will focus on making new resources ready for the launch of the new linear A-Level next year. I will also be blogging about the various courses and exam boards offering Biology A-Level as my department make their decision about which to choose.
Thank you once again for all the positive feedback and please let me know if there’s anything else you’d like to see on mrexham.com!
