No topic is considered a grade 9 topic. To create a grade 9 question, you must take topics and introduce a higher level of problem solving with curve balls hidden throughout. You must be able to 'spot it'. 

All of the questions in these grade 9 papers have been created to test and improve problem solving ability. They raise awareness to curve balls and misconceptions giving you all the tools required to achieve a grade 9.  I use these in my own classes. Last year, none of my students had a target grade 9, only 6 had a target grade 8 and the rest were 7 and below. The class went on the achieve 13 grade 9s as they became familiar with grade 9 style questions. Practice these questions and your chances of achieving a grade will increase!
