Paper 2s and 3s in gcses

When ideally should I be properly revising for paper 2 and 3s for gcse because atm I'm focusing on paper 1s and all of my paper 2s and 3s are in June except for RE and English where for RE paper 1 and 2 are in may and for English lit p1 and 2 and lang p1 are in May
How do I structure my time so that I can make the most out of the week in may half-term and fit in the rest of the papers for my subjects as all of may is pretty much paper 1s

Revise for Paper 2 in Easter hols (2 weeks) then the 2 weeks you have going back to school, revise Paper 1, as this will be first exam
