Topics and Structure of the Papers

Ask your class teacher to confirm these details

Key words of advice

Know in detail what you need to revise
Map your revision progress using tools such as the sortable syllabus found under on the syllabus page

Know how to address your answer to the question

understanding command terms is critical, use the relevant resources on general resources to make sure you understand them fully.

Have a set of quick study tricks
By this acronyms and way of remembering simple ideas, e.g. OILRIG - Oxidation Is Loss, Reduction Is Gain (of electrons)
Some ideas from John McMurtry

Learn a successful approach to data analysis

  • Read the information carefully
  • Highlight key points as you read the question to help get your head around what its telling you
  • Write a bullet point summary of the graph before answering the question
  • Use a ruler to read graphs
  • Give units in your answers where data/numbers are required
  • When comparing and distinguising don’t write unlinked descriptions or just quote values, make true comparisons, e.g. ……is larger than ……….. / ………. happens more frequently than …………
  • Be concise, don’t waffle

Revision Resources

BIS provides excellent revision resources - make sure that you make good use of them:

General advice on revision

Webllinks to revision advice:
  • Exam skills by i-Biology (for the old syllabus, but still contains lots of relevant advice)
  • Mr Damon's guide (to preparing for exams)
