Biology revision: Guides that might help

Can you identify your friendly neighbourhood fungi? Need help drawing a line between homeostasis and Homo sapiens? Yet to find out what you're (literally) made of?

Don't panic! Biology exams are round the corner, but here are five handy revision guides that may help you adapt and survive.

We can't guarantee these topics will come up, of course, but we chose a few we thought might be useful to get you started. Click on the images below for the relevant revision guides, and we’ve added some extra articles just next to them, too.

All our Biology guides are exam board specific so click here to find your GCSE exam board.

Cell biology

Cell biology

All organic things are made up of cells - so start small!

Brush up on the basics of cell structure here. We also have cell division and control. You will need to know the different types of specialised cells and their roles. Refresh your memory on how to observe them under a microscope.

Inheritance and genetics

Inheritance, variation and evolution

Now let's go even smaller...

Within your cells lies your DNA. Find out what DNA stands for, what it contains and why you need to know. Then study the detailed breakdown here. Understanding DNA is important for genetic research, forensic databases and exam revision alike!



Darwin said it's survival of the fittest, but what did he mean by that? Biology expands to plant and animal kingdoms - learn why it's important to classify flora and fauna, why a species undergoes adaptation and how every living thing impacts its environment. Look out for spiders!



Plants need to eat too!

Photosynthesis is a staple biological process in any flower's diet. Revise how cells turn sunshine into sugars, its uses and its limits. Not magic, but science!

Practical skills

Practical Skills

It's important to revise practical skills as well as content. See this guide to understand each step of an experiment and how to interpret data. Even if you're not doing an experiment, it might pop up as a scenario for an exam question in a written exam.

A practical skill we often overlook is exam technique, including keeping calm. This also applies to revision - take a deep breath, stay organised, and manage your time effectively. You've got this!
