The video below talks about the 2023 classes. The arrangements in 2024 are slightly different and the Olympiad classes now offer a 'regular' and 'advanced' option.
The Regular option will be aimed at students taking the Olympiad for the first time. The advanced option will focus mostly on the harder section B problems.
Students may want to attend more than one set of classes (eg Kangaroo and Regular or Regular and Advanced) but should only register for one of each as the content will be the same across each type of class.
