Independent study is about asking your own questions of material and then researching these questions.
Discovering things about your own learning style allows you to work out in what situations you might need to work harder.
Developing a reading strategy is important to help you cope with the reading required at university. It is important to read with purpose; ask yourself why you are reading the material.
Make notes on material you read. This helps you engage with the material and check your understanding of it.
After you have read the material, ask yourself further questions: is this useful to me? How does this fit in with my own ideas etc.?
