Read and make notes:
Making notes turns reading into studying. Notes should be brief, clear and
helpful.
To help your understanding:

, • rewrite or summarise what you have learned (avoid copying what
you have read);
• note down any questions your studying has raised, either to ask
your tutor, or to develop into further research.
To help you to remember:
• sum things up to improve long term memory;
• write things down to aid motor memory;
• use colour, images or patterns to help visual memory.
To help you in your assessments:
• record where you will find information (e.g. page numbers);
• keep your notes organised and easy to navigate;
• highlight where further reading and research are needed, including
any recommended or further reading;
• use your notes to help you get started on your TAQs.
Read the Specification:
So that you will know the criteria you will be assessed on please
read the unit specification in my courses on the Materials page.
