STUDY CHECKLIST AND ASSESSMENT
OBJECTIVES
,Instructions
Regular revision throughout the year is essential. It’s vital you keep a track of what you
understand and what you don’t understand. This booklet is designed to help you do this.
Use the following key to note how well you understand the work after your revision. Put the
letter R, A or G in the table. If you place an R or an A then you should make a note of what
you are struggling with and the end of this book under the relevant section and seek help
with this.
Key
R = Red. I am not confident about my knowledge and understanding
A = Amber. I am fairly confident about my knowledge and understanding
G = green. I am very confident about my knowledge and understanding
