And on a more curious note, there are now high schools which have done away with the failing grade altogether, and now pass anyone. So the concept of "not failing a test", well, blame public schools who like to have positive numbers and are pressured by all sides to let a student who is otherwise . . . not up to standard . . . slide through. Because everyone has a different learning curve and we shouldn't dare punish those who learn slower, so let's pass them now rather than later.
I could rave about schools for ages, but . . . why?
Also, I so need to take my driving test soon. This is the last time I let my actual license lapse
