DD1 did GCSEs last year. Disorganised dyspraxic so I oversaw revision. This is what we did:
Start with list of topics for each subject.
Then estimate time needed for each topic.
Add in time for practice papers (science & maths esp) and 'last minute review everything' the day before each exam.
How many hours can he do each day (better less e.g. 4 and realistic, than say 8), make sure breaks are built in, short ones every 45-60mins, plus longer ones. breaks for eating, exercise, socialising.
Check total hours needed v planned and adjust so it fits.
Allocate which subjects (and topics) will be done each day taking note of when the exams are. Mix enjoyable ones with less fun ones.
Revision needs to be mix of things like
- reading the topic
- taking notes / drawing diagrams / whatever
- online quizzes
- listening practice for MFLs
- practice papers
- being tested by Mum
All sessions have a topic based goal.
So e.g
session 1
45 mins Chemistry - notes on structure of atom etc
45 mins French listening practice
45 mins Maths questions on fractions
later in day session 2
45 mins Chemistry practice questions on structure of atom
45 mins Geography notes on volcanoes
45 mins Biology BBC bitesize revision on DNA
Use plan as a guide, and let sessions be moved around, provided they are all making sensible equal progress.
