You need to know some maths for A level Biology. This includes knowing how to interpret averages (mean, median and mode), ranges, and standard deviations to work out whether an experiment can be said to have shown an effect or not. Master this early on and it will not help you with exam questions, but also make it easier for you to learn the bits of the course that are explained using these statistical methods.

Some concepts turn up again and again in A-level biology. Taking a little time to ensure you really understand these key concepts from the start can save a lot of effort overall.
Surface area to volume ratio (SA:V) is vital for understanding a wide range of topics including transport across cell membranes, gas exchange, digestion, heat exchange, and mass transport. SA:V explains why the inner membrane of a mitochondrion is folded, why elephants have big ears, and why jellyfish don’t need blood vessels.
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.
