Has anyone come across a bank of resources which collate the now increasingly popular shape and algebraic expressions questions please ? It would take a while to trawl through the EDEXCEL papers to find them all. My year 11 just did appallingly on one of these questions ( isosceles triangle - Nov 2013 ) in a mock. I want to address the weaknesses now before the last chance in June 2013. Any help would be appreciated.
