What i plan to do is to laminate the periodic table, electrovalency table and other general rules,etc and stick them in a high visibility area around the house: bedroom posters, toilet reading material (lol)...
Have them laminated so that you can use a white bord marker and write all over it if you need to.
For Unit 3 AOS 2 - organic chem - use a whiteboard to sketch out the structural formulas: much better than using pencil/rubbbing out when you make a mistake.
Data booklet is a must.
Start prac exams around end of term one (not now). Throughout term two, you should pace yourself with maybe 1-2 exams per week; until then, study ahead using old checkpoints/neap/A+ notes/other textbooks.
Make sure that you know each topic in depth and practice relevant (and sometimes harder uni-level) questions. For exams, make sure each is completed to as much accuracy as possible and possibly get some else to mark it for you.
Sometimes study groups work - teaching others, i find, is an extremely effective way of realising how much you actually know your stuff.
Good luck to us all!
