Well that's rather nice of you! But in that case, where did the table come from? I'm thinking this would be *great* to use as an example in GCSE statistics lessons. Or, indeed, in general…

Looks like it needs 10 downloads, one for each maths grade. Then for each grade fill in a database column.

If you're looking for light, fluffy entertainment then it's definitely not for you. It's very dystopian. However, I think it's very well written and looks really good.
This is probably just me, I'm not really a great comedy fan, but I do like high-concept scifi.

I've been watching it and, yes, there are strong horror components to it. However, Alien: Earth is so much more than that. There's a humongous subplot (or is it the main plot?) about achieving immortality and it's set against a background of five megacorporations owning… everything.

To me this entire concept that memorising and regurgitation constitutes some form of “learning” (let alone understanding) is absurd.

Regurgitation without understanding is pointless. You'd be no better than an AI. In fact worse because AIs don't forget, are cheaper and have a broader knowledge base.

Agree. At the secondary school I went to in the 70s if you disobeyed you got spanked by the very teacher who was (too) later convicted of sexual abuse. Yes Larner, we remember you!
