1 ring binder, plastic wallets for each subject, homework and paper. write on paper in class then end of week file it away in seperate lever arch files at home and write notes as i go along from them. I suggest writing manually as you'll actually be conciously thinking whilst writing it down, but if you have patience to do both then why not, as long as it helps. As for stationary basically everything you used for GCSE's but may want to upgrade your calculator if it isn't a proper mathsy one already
