Revision tasks to be completed

There are lots of techniques you could employ for revising, including:

• Make sure your notes are filed in order (see textbook for chapters). • Use the DLS powerpoints, video clips, worksheets and homework sheets from Year 10. • Create a mindmap for each section/unit. Use the CGP revision booklets to help with this. • Use the PG Online textbook chapter questions and end of unit tests to identify any knowledge gaps. • Use the CGP workbooks to test your knowledge (write in pencil so you can amend any mistakes and keep your booklet neat for revising). • Look at your end of unit assessments and see where you did well and where you had knowledge gaps or needed to expand on your answers.

Other tips

What you need to bring to the exam:

Normal writing and drawing instruments (you can use the Iso Sketch drawing tool) • A calculator • A protractor

Tips in the exam: • READ THROUGH THE PAPER FIRST! Identify questions that are ‘easy’ to answer (i.e. you know the answer), then go back and answer these first. • If you get stuck on a question, MOVE ON! Don’t get fixated on it – you can always go back to it later, if you have time. • Use black ink or black ball-point pen. Use pencil ONLY for drawing. • Marks for questions are shown in brackets – this should also give you a good idea of how much you need to write. Show any calculations where necessary. Use paragraphs and/or bullet points. • Answer all questions in the spaces provided (don’t write on blank pages). • Do all rough work in the paper. Cross through any work you do not want marked.
