Basically, instead of trying to stick to a specific time frame, just choose a few topics to revise each day. I found this much less stressful, as I didn't have to worry about running out of time and messing up my schedule if a topic took longer than I thought to learn. I'm afraid I no longer have my A2 revision timetable, but I hope that gives you an idea of what it was like (I assume you're doing GCSEs, but my advice still applies)
