Often the student has already mastered most of the topics before they reach high school and online platforms like Maths Pathways and Maths Online can be configured so that if a student answers both answers correctly for a topic concept (eg. factorisation of a quadratic equation), the program allows the student to skip over that topic. My son used these programs and with Maths Pathways in Yr 7, he skipped all of Yr 7, almost all of Yr 8, over 70% of Yr 9 and more than half of Yr 10, completing Yr 7-10 content in six months (even for the topics that the student does have to cover, if the student gets the first two post-topic questions correct, they don’t have to do 10-20 questions which exercises in textbooks usually contain). Maths Pathways content only went up to Yr 10 back then, so he switched to Maths Online for Yr 11 & 12 content and scored 98 in HSC Adv Maths in Yr 9 and 98 in maths extn 1 & 2 in Yrs 10 & 11. The best part of this story is that his local high school was ranked about 440th in NSW for his cohort, so in this digital age, bright students can achieve from anywhere.
