The Cambridge Assessment International Education (CAIE) has cancelled its May-June exams and decided to switch from “exam to school-assessed grades”, schools that offer the curriculum said. Several schools in the city that follow the CAIE received an email late on Friday. “In view of the increasing number of Covid-19 cases in the country, we have decided to switch Cambridge International Schools in India, from exams to school-assessed grades, so that students can receive certification and progress with their education,” said an email from The Cambridge School quoting the mail from CAIE. At least three city schools, The Cambridge School, Bridge International School and Vidyanjali International School, informed students of the change on Saturday.
