Welcome to MrExham.com, an online blog designed for students, teachers and anyone who loves anything Biology!

The primary aim of my blog is to create an information resource for pupils studying Biology IGCSE, A Level and the International Baccalaureate (IB). I will also be regularly posting links to anything in the Biology world that I find interesting, be it news stories, articles, videos, or games, in the hope that Mr Exham will inspire YOU to Make Sense of Biology.

If you have any questions please email me.

Mr Exham on iBooks

I am very pleased to announce that my first eBook has been published on the Apple iBooks store.

It has been designed for iBooks and will work on iPad, Mac and iPhone (depending on operating system).

It is hopefully the first in a series of books covering the IGCSE course. This first book is FREE and covers the sections on life processes and classification. It contains interactive multiple choice questions at the end of each section and practice diagrams to label.

Why not download it now and give it a 5* rating?

IGCSE Biology – 6 Marker Question Revision

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.

IB Update

The IB Biology syllabus has been updated this year and to reflect that I have made a new summary of how the course now works.

A Level Biology 2015 – Edexcel B

It looks like mrexham.com will be specifically making resources for the Edexcel Biology B course starting in 2015. Many of the courses have overlapping topics so many of the resources will be relevant for other courses as well. For now please enjoy this useful outline I have made for the Edexcel Biology B course.

IGCSE Revision Diagrams

One of the most important parts of IGCSE Biology is to be familiar with the key diagrams. I have therefore created a great revision PowerPoint that contains the 25 most important diagrams on individual easy print slides. Also included are all the answers. If you are a teacher these are great for testing your class, if you are a student you can print multiple copies and try them until you get them all right. Click on the image below to purchase this new resource:

Included in the presentation are diagrams for: the kidney, urinary system, digestive system, reproductive system, the leaf, the eye, a motor neurone, the circulatory system, plant cell, animal cell, sperm cell, menstrual cycle, nitrogen cycle and many more.


Happy New Year

HAPPY NEW YEAR to all my followers. And best wishes for the new school term.

Merry Christmas from Mr Exham

Biology A Level 2015 – Content or context?

By now I’m sure you will have all looked at the various options for which specification to choose from. For my department the first question was did we want to choose a context based or content based course. The traditional courses are content led, this means that the topics are discreet and are just taught as individual topics, rather than the context based courses which give a context to each section of the specification. For example, the context may be the blood and you would teach various topics from that context, such as cells, immunity and hormones.

As teachers we always give context to what we are teaching and in this way the content based courses are more flexible as you can arrange topics how you want and apply your own contexts where relevant. However, the content in the context based courses seems to be more current and interesting.

Once you decide which approach to take, the task of deciding which exam board to choose is actually quite tricky. Now that coursework as such has been removed from the qualification, the differences between the options are very slight. The content is much the same across all exam boards and so it just comes down to the type of assessment, style, resources, loyalty and personal preference.

Please fill in this poll and write in the comments your opinions and thoughts regarding this important decision.

New TEDEd Lesson

I have just uploaded a new video and TEDEd lesson on the digestive system which I have been putting together for a while. I am also planning on updating my older video resources to bring them more up to date.

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.
