I revise 2 subjects every day, each for 1 hour. So 2 hours altogether :(
I made a timetable, so I know which subjects I should be doing. But I do more chemistry and geography than biology, RE and physics because I have more work to learn in those.
So anyway, I think 2 hours a day is a good amount. Any less than that won't be enough. And do 2 subjects every day.
I dont know what GCSEs your doing, but I will make a timetable as an example (by the way, I expect best answer). Do each subject for 1 hour :
Monday - Health and Social + Physics
Tuseday - Biology + Chemistry
Wednesday - Chemistry + Physics
Thursday - Health and Social + Biology
Friday - Physics and Biology
Saturday - Health and Social + Chemistry
Sunday - Do any subject you think you need to revise more on. At least 2 hours.
Now give me best answer please :D
