2022 EXAM PREP CLINICS
Science Clinic is hosting prelim and final exam preparation clinics between
August - November. Our national team of subject experts will be explaining
the core theory and practicing exam questions for the entire Matric
curriculum. The clinics are hosted interactively on Zoom so that students
can ask questions and receive individual explanations throughout the
courses. The primary focus of the final exam crash courses, which will be
hosted on the two days before the respective NSC exams, is to practice past
paper questions.
Course dates are provided below. To see the exact time schedule and topic
allocations, visit our courses page and click the + icon next to a course.
