This article is for anyone who is totally confused by mitosis, or who hasn’t yet started the topic.

Mitosis is part of cell division. It explains how multicellular organisms grow and is vital for understanding the challenging topic of autosomal linkage. Mitosis is also similar to the first half of meiosis; learning mitosis first will make meiosis much easier to understand.

Remember that for A level biology, you always need to understand why, as well as how. So, get a strong grip of the fundamental concept of mitosis before you try to memorise the details. Understanding the purpose of mitosis will also make it a lot easier to remember the individual stages of the process.

A variable is any value that does/might change during an experiment. Variables can include things like pH, temperature, colour, or the concentration of substances. The amount of time that has passed is a variable, as are rates of reaction.

Your teachers will take you through the course material. Hopefully you’ll be able to follow what they’re saying, and maybe you’ll copy down notes in class and then make flashcards to help you remember these things. But that’s not enough to get a good grade. There are some things you need that teachers don’t tell you – because … well, they can’t. Some things can’t be told.

Can you spot the problems with these A level Biology exam question answers? These bloopers come up a lot - check you’re not going to make the same mistakes.

Have you ever listened to a talk where the lecturer explained everything so clearly that following their train of thought was effortless - everything made such perfect sense, and flowed together so well that it was a pleasure to listen to? I’ve been to talks like that, and loved them. I’ve gone home rhapsodising about how I learned so much. And then someone asks “What did you learn”? And - I realise there’s no residue of the talk in my mind. I can remember the experience, but not the information.

Understanding and remembering all the information required for A Level Biology is a real challenge. So anything that reduces the workload and overall effort required must be a good thing.
