How to revise!??

My question is how do i revise for my gcse subjects im taking this year.. do i revise the lessons ive learnt on the day when i get back home (doesnt work for me) or do i make a revision timetable.. (which im also confused about too).. good advice please!

If anyone can help me to make a revision timetable, that'd be great!
This is my normal school timetable:
monday: english, citizenship, spanish
tuesday: spanish, science, maths, history
wednesday: maths, english, citizenship, science
thursday: history, english, science, maths, spanish
friday: history, maths, english, science

We do 6 subjects a day however i've taken out the subjects im not taking gcses for eg. pshe etc.

NOTE: i can only revise 1-2 subjects per day (HELP!)

monday revise: english and citizenship
Tuesday: spanish and history
wednesday:maths and science
thursday: maths and english
friday: science and history
sat: citizenship and spanish
sun: most difficult subjects
i have major issues revising too, i get distracted easily, no matter what i do i can never focus or get my work done but hopefully this helps

You could use the TSR revision timetable planner in the revision section. Good luck!

Make sure you do past papers. The questions you answer incorrectly should be your priority. Take breaks every 20mins or so. no high sugary things like fizzy pop or caramels. A brief snack like nuts or something! hope this additional info helps :-)
