Revision tasks cover topics which students should know from previous studies and form the foundation which this course builds on. They do not cover examinable topics but make studying examinable topics easier.
Revision tasks are optional and if a student is confident in his/her knowledge of the topic then they can miss it out but they must come to class prepared to answer questions relating to these topics.
Consolidation tasks are not optional as they cover newly learned course material which will form the basis of the final exam.
These are only the Mymaths.co.uk tasks which have been set, though the sheet does mention a couple homework sheets. There will be more written homework throughout the course to help assess students progress and understanding of the material.
[NB: Hard copies of Mymaths.co.uk tasks can be obtained from myself for those without access to the internet or who are experiencing internet problems.]
