i'm in yr 11 now but i accelerated geo so i did prelim geo last year.
no publishers do any study guides for yr11 geo (sadly...it always has been shunned by society)
basically, the best resources i found for studying geo were the textbooks (obviously) and stuff on the net. remember, the extended responses in geo exams are usually worth over half the marks, and teachers absoultely love it if they're jam packed with stats, tables, graphs, quotes, diagrams, etc. so go on the net and try and find this stuff, especially for the second topic --> human geography.
