GCSE revision planner
Your subjects, your exam date, and how many sessions a week you can actually manage. You get a week-by-week plan you can print, and where we have a real activity for a subject it is named in the slot.
This plan is arithmetic on the numbers you type in. It is not a measurement of anything and it is not advice about how much revision you need: it spaces the subjects you chose across the weeks you have.
What this does not do
It does not know how much revision you need, because nobody does. It spaces what you chose across the time you have.
It suggests an activity only where we have one for that subject. Where we do not, the slot names the subject and leaves the rest to you.
It saves nothing. Close the tab and the plan is gone unless you kept the link.
For the reasoning behind spacing subjects out rather than blocking them, see retrieval practice for GCSE.
