I've reached the stage where I'm now revising 7 hours a day to cover everything contentwise and for pastpapers. I've finished Stats and Unit 1 Chemistry so doing past papers for them on a regular basis now. I'm most woreied for Chem 4 and 5 though because the stuff is so hard to remember! Hopefully I've finished all of Unit 5's content by the end of April.
I've got 6 exams left to finish up, so i've set a target to complete everything for 3 exams for each month for March and April. May will be just past papers and looking over everything one last time. OnceI've finished the content for each exam as I roll through I'll attempt past papers erstwhile.
