Some time ago the broadcast timetable for memo discussions and the revision programme during the holidays was released (see this post). However, the slots for physical sciences and life sciences will swap. Hence, the physical science broadcast will take place on 1 July at 08:00 to 10:00 and 10:30 to 12:30.
Please make your learners aware of it. The June exam papers are going to be discussed for revision purposes and it might help them in their preparation for the end of the year.
