Sep 27, 2017 at 20:41 comment added anotherdave Why are they on the syllabus feels like it might be a more interesting questions. Why ought they be able to make them? — Because he'll have taught them to (because they're on the syllabus).

Sep 26, 2017 at 17:26 comment added Mindwin Remember Monica @wraithleader your knowledge of finding the concentration of HCl allows you to see the world with much better understanding. Just like you also would if you knew why the petunia bowl thought "oh, not again" when it fell on the skies of Magrathea. The knowledge in itself may be useless, but it leads to a deeper undestanding of the fabric of the universe. And probably everything else.

Sep 26, 2017 at 15:43 comment added MissMonicaE I think you're misunderstanding Slughorn. He's not saying "You ought to be able to make this potion because it will help you in your life." He's just saying "By the time you're done your NEWTs you ought to be this good at making potions, because otherwise you'll probably have failed your NEWTs anyway.
Sep 26, 2017 at 15:19 comment added Jeff To be fair, it doesn't say that you need to learn to make that particular potion for your NEWTS, but it does give a relative difficulty of creating the potion. It is certainly possible that creating such a potion would be on the standard test, but it is not a given.

Sep 26, 2017 at 14:34 comment added Wraith Leader I mean, I may have jumped the gun, the way you ask the question may leave it open to a good answer. "Why would anyone need to be able to make it?" asks for the use case, not why everyone in the school would need to be able to make it.

Sep 26, 2017 at 14:28 comment added sudhanva Ah yes, the dreaded titration. I suppose you are right and there is no correct answer for this one..
Sep 26, 2017 at 14:22 comment added Wraith Leader I'll never need to know how to titrate NaOH with HCl of unknown concentration to find the concentration of the acid in my profession or in my personal life, but I still know it. Sometimes you learn things in school you won't need in the future. I don't see why there would be a practical application for everything in Hogwarts either. When are they going to need to transfigure a needle into a match or a hamster into a teacup? There's also the argument that knowing how to make it/what it looks like could help you avoid it.
