15% needs hospitalization (some places in UK this reached over 30%)
Sure it's just a typo but you say reached as in past tense, cases might be as stated but it's still early days and it's rising all the time. Because of the UK government going for a slowing down approach rather than Italy's Lockdown cases are not even expected to peak until 12 weeks time and i have heard figures as bad as 60% getting the virus (albeit most mildly) with a worse case yet very possible 80%.
School Exams have been cancelled for this school year and pupils will get grades based on what the teachers estimate they would of got. This is no small thing as it can shape someone's future working life and even if a good grade is giving future employers will be well aware looking at their applications that their school year was the year which meant they didn't need to sit exams so the working under pressure aspect of an exam hasn't been proved!
Exams wouldn't even be until July/August so to already officially cancel them despite there importance shows we are expected to be in this for the long haul!
