UCB News- What is toxic stress? by UCB News Team published on 2018-06-21T16:17:28Z A union doesn't think universities in England should use predicted grades to make degree course offers to students. The University and College Union says no other developed country uses such a system of forecasts for university admissions and says research shows as few as one in six predictions are right. A-level predictions are currently used when deciding on an offer. UCB's Vicky Gibbens has been speaking to Dr Margot Sunderland from the Centre for Child Mental Health about how exams cause toxic stress and whether she agrees with the union.
