Goodness! nowhere do I see that OP wants to do his ground school before anything else. I have just come back from my hospital and seen the parks full of people, the tables outside closed pubs full of people, and the internet full of younger people saying they dont care. The point I am trying to make is that everyone must be locked down now. As to whether it will be over in 20 weeks, well we dont know but it wont be if we are not serious now.
