All assessments (excluding the final IGCSE examinations) are carried out during regular live lessons. We assess student performance through tests, homework, in-class activities, exercises, and worksheets. Students perform few practicals because of the virtual nature of this course. However, our MA/PhD qualified subject specialist teachers try to incorporate as many safe practicals into the curriculum as possible. Student safety comes first. We ensure that each practical conducted by Cambridge Home School Online requires safe household materials and poses no risk to students. At Cambridge Upper School, we encourage students to develop a scientific mindset when approaching everyday phenomena. Students become aware of how science comes into play around them. This insight helps them understand scientific queries, solve problems, and become critical thinkers with strong reasoning abilities. Students are required to possess certain materials, including an apron, safety goggles, and a tray for conducting practicals. We may require additional materials. However, they will always be announced a week in advance so students can easily gain access to them. We also provide students with a permission slip that their parents must sign. If a student does not wish to perform a practical for any reason (parental disapproval, inability to acquire the required materials), they need not worry. Our teachers demonstrate all practicals so students can understand the activity even if they are unable to perform it themselves. We also provide catch-up lessons. Students can access our online library of past lessons at any time to get up to speed with the rest of the class.
