General websites AS & A2:


Have no fear, the links below will provide lots of advice & practise. If you get stuck, bring the calculation to your teacher for some help.
    • Basic calculations - You can't survive 'A' level Chemistry without an understanding of these calculations. Test yourself on this excellent site.
    • Titration calculations 1 - a 'model' answer and some practise questions.
    • Titration calculations 2 - Very useful 'worked examples' plus general advice on apparatus and technique.
    • Titration Quiz - test yourself. Have a pen, paper & calculator handy.
    • Enthalpy Calculations - Lots of practice calcuations. If you think you might need a teacher to check your work, don't forget to print the questions!
    • REDOX calculations - Mainly A2 level. Practice calculations with related answers that are EXPLAINED. Very useful revision tool. BE CAREFUL - have your syllabus handy so that you know which calculations are AS, and which are A2!
    • Mass to Moles - How to convert the mass of a substance into moles.
    • Molarity - How to work out the molar concentration of a solution. You can also practise these calculations by clicking here.
    • Text books - If you think you may need more help with your Chemistry calculations, you might want to have a look at this book.
    • Calculation Exam tips - an 'A' level examiner has written a guide for students on how best to present your calculations to maximise your marks. Well worth reading.
  • Exams:
    • You may be asked to write a plan for an experiment. If you click here, you'll find a frame that might help organise your thoughts.
    • Read how to answer your exam questions in the best possible way - this is written by an experienced examiner, so take his advice seriously!!
    • Advice on preparing for exams.
    • Have a look at these bad answers. If you understand why they are wrong, you'll do much better when it's your turn.
    • REMEMBER, always have your syllabus at hand. Some of this stuff might not apply to you!!!
  • Revision:

    Note that the following sites are very useful, but may not be explicitly designed for the OCR syllabus. When using them, therefore, have your copy of the syllabus at hand.
    • S-Cool - brief, but functional. A good starting point, but you should look for greater depth by using the websites below.
    • Chemguide (AS mainly)
    • Doc Brown’s ‘A’ level pages. The Doc has written some quizzes here. Good for a quick check of knowledge, but remember you'll be asked to apply what you know too.
    • More revision notes here (OCR specific). They're brief in places, but worth a look.
    • OCR-specific Quizzes. AS & A2. Take the time to test yourself. Bestchoice is more detailed, but this one will give you a good work-out on the facts.
    • Revision World - Good background especially for A2 students.
    • Revision NOTES. AS & A2 revision notes in pdf. Scroll down for quizzes and animations of key concepts. REMEMBER, you need to USE your notes by making concept maps, condensed notes, cue cards (whatever works for you), then test yourself with past papers (see your teacher and the sites on this page).
    General Interest:

    Science audio:
    • 'In our Time' - Fascinating and accessible discussions with working scientists on a wide range of topics ranging from current research findings to the history of science. Well worth a listen.
    • If you are interested in the evolution of life on our planet, have a listen to 'An Earth Made for Life'.
    • Some scientists believe playing Mozart while you are working increases your ability to learn (maybe you want to give it a try). Listen to the 'Mozart Effect' to see if you agree.
    • 'Frontiers' explores new ideas in science, meeting the researchers who see the world through fresh eyes and challenge existing theories. This is what scientific research is all about.
    • The human mind is a complex puzzle that scientists have been trying to solve for thousands of years. Thanks to chemists, biochemists and pharmacologists (who are basically chemists 'in a hat'), the mystery of the mind is beginning to be unravelled. One of the great brain researchers of the 21st century, Prof. Ramachandran, has given a series of wonderful lectures that describe what scientists have found out about our brains. You can hear the lectures here.
    • What can I do with an ‘A’ level in Chemistry? Lots, actually.
    • If you’re thinking of going to University, try PUSH for some independent advice, or 'Aim Higher'.
    • UCAS - Higher education info & applications.
    • Not sure what you want to do at Uni? Try the Stamford test, it might help.
