General

A levels and other examinations were always unfair, yet perhaps it took a pandemic to see it. You can be amazingly clever, but if you're disadvantaged then there is a high chance that you'll have issues with stress deregulation in your body. What that means is, that for your body, an increase in stress will defocus your brain and hinder exam performance. For a student who lives with more affluence, there is a good chance (yet not a guarantee) that their stress response is well regulated and in exam conditions their brain achieves a higher level of focus. So, maybe the government didn't do such a bad job of their algorithm (though there are heart-breaking stories out there for sure that need correcting), maybe it's actually evidence that unfairness has been "baked into the cake" for generations. Perhaps that's the "big lesson" the government needs to ace.
