If you are thinking about planning your revision, below is a model mind map which might help you plan for the weeks approaching an exam. It has 6 weeks on it - so you can either use it for 6 weeks, leaving time for another period of planned revision or add extra branches for the extra weeks.
The idea is to set topics for each week, and then further break down the week into daily tasks (making allowance for the likely demands on your time - days/evenings when you won't be able to revise - or days especially set aside)
The MindMap below can then serve as a template for your own planning Mind Map (which can be hand drawn - or developed on a computer - for more details go here.
