This provides some top tips on how best to revise for Biology at GCSE/IGCSE, IB and A Level.
Start your revision early by going over each topic after your lesson and using the information to prepare flash cards, summaries of key points and mind maps.
Draw up a revision timetable. Make sure that this is realistic and factor in regular breaks; half an hour of fully focussed revision is much more effective than two hours that is unfocussed.
Do something completely different during your breaks to allow your brain to absorb information– do some exercise, listen to music or make a hot drink for example.
Prepare flash cards giving a key word or phrase on one side and an explanation on the other side. Use these to test yourself regularly. As you approach your exam, separate them into those that you know and ones that you still need to learn so that you can visibly see progress.
Use your time effectively. If you have 10 minutes free during the day test yourself using flash cards. The more times that you revisit a subject even for a short time, the more firmly it will be embedded in your long-term memory.
Summarise each topic as the key ideas as this is what you will need to get into your examination answers. Being able to write concise answers will improve your time management in examinations.
Draw mind maps for each topic linking key ideas. Try to draw these from memory during revision to find out the things that you remember well and those that need more work.
Use coloured pens and highlighters as this enhances recall.
Devise ways of remembering difficult terminology. For terms that have similar names but different meanings such as mitosis and meiosis or glycogen and glucagon think up a word, a phrase or an association that will help you remember; something silly usually works well.
Practise writing exam questions. Do not just look at exam questions, commit to writing down an answer and pay close attention to the mark scheme to make sure that you have included everything required for full marks.
Do not leave difficult topics to the end. If you tackle these topics early you will have time to revisit them more than once which will help to embed the knowledge more securely.
Practise good time management and work to a study schedule. Prepare a revision timetable and include difficult topics early so that you can revisit them several times before the examination.
Review lessons after each class to reinforce your understanding of key concepts. Use textbooks and online resources to consolidate your knowledge.
Be actively involved in your revision by preparing concise revision summaries and flash cards that include key words and concepts. Revisit these regularly to check your learning. The ability to write focussed answers will save time in examinations.
Use mind maps to reinforce links between different topics and to give you an overview of the whole subject; use colours as this has been shown to enhance learning.
Teach a friend; you cannot achieve this unless you know and understand the topic thoroughly.
Use past paper questions frequently to apply your knowledge to unfamiliar situations and use the mark schemes rigorously. Precise wording and use of key words and terms is essential for achieving high marks.
Practise data analysis skills using past paper questions and questions from textbooks, as questions on paper 2 focus on data analysis and interpretation from unfamiliar situations. Where relevant remember to refer to data given in the question.
Do not neglect mathematical skills; for example, practise questions on scale by studying a variety of electron micrographs and be familiar with unit conversions.
Practise multiple choice questions and use elimination techniques to make an educated guess if you do not immediately know the answer as this will increase your confidence when in an examination.
Make sure that you get enough sleep and eat nutritious meals. Take time to relax between revision sessions.
Review your notes after each lesson. Make sure that you fully understand each topic by reviewing your notes, consolidate the information by referring to textbooks and online resources and condense the information down as flashcards and revision summaries.
Use your flash cards for key words and definitions as key words score marks in examinations. Check your recall frequently even for five or ten minutes a day as the more times that you revisit a subject even for a short time, the more firmly it will be embedded in your long-term memory.
Use mind maps as an alternative way to summarise course content; a variety of approach helps to maintain focus and reduces boredom and an ability to summarise topics concisely will improve your time management in examinations.
Draw summary diagrams particularly if you are a visual learner.
Use different coloured pens and highlighters in your notes as research has shown that using colour enhances recall.
Revise core practical exercises thoroughly with particular emphasis on critical evaluation of methodology as this frequently comes up in examination questions.
Teach someone else. Pair up with a friend and choose a difficult topic to teach. You cannot achieve this unless you know and understand the topic thoroughly.
Practise applying knowledge to different and unfamiliar scenarios by completing past examination questions. Do not just look at exam questions, commit to writing down an answer as you would in an examination and pay close attention to the mark scheme to make sure that you have included everything required for full marks.
Pay attention to critical analysis of data including application of statistics for higher level marks.
Use mark schemes rigorously as exact wording and use of key terminology is important.
Read examiner reports as these summarise common errors and omissions and some include model answers.
Do not ignore calculations. Make sure you are totally familiar with unit conversions, that you understand simple statistical interpretation and can calculate percentage change as each of these come up regularly in examination questions.
Ask a teacher or tutor to mark longer answer questions as mark schemes for these questions can be quite complex.
Include wider reading to link your knowledge to the real world. You will find relevant articles in the New Scientist for example and useful podcasts produced by the BBC. This will help you to remain engaged and motivated and is important if you aspire to achieving an A* grade.
Make sure that you get enough sleep and eat nutritious meals. Take time to relax between revision sessions.
