“It teaches you as you go so you are able to test yourself, but you aren't expected to already know everything. I love how the problems are so creative, and entertaining to read. The tutors are also really friendly and respond quickly to queries.”
“Working on a challenge for hours, racking your brain and thinking about it for hours more, and then the feeling of success and satisfaction when you run it and it's correct! I love the little adrenaline rush you get when all the green ticks pop up!”
“Students who have normally been less than engaged in Tech are suddenly immersed in it, not only managing to work through the problems and frustrations but also helping each other. The collegiality and collaborative environment is fabulous.”
Sujatha, Technology Teacher
“Not only did the challenges allow [students] to develop new skills, it also improved their self confidence as they were able to see the improvements they made as they worked through the problems. Our school based data shows improved computational thinking with improved results in external competitions.”
Linda, Technology Teacher
