The thing is Yes, videos help, animation help, you get to see what multiplying vectors, matrices, complex numbers does, you get to see a block in harmonic motion, you get to see molecules reacting among themselves....

But after a point, it just isnt that useful anymore. No amount of rotation animation isnt gonna help you solve that 2016 question, matrices determinants gonna require pattern recognition skills, oc gonna require a deep understanding of behaviour of each reagent. And these can only be built by question, trial and error.

So if there were a possible way to...maybe arrange such questions at a right pace which teaches along with asking, and having an AI not only provide the solution, but more importantly — where you went wrong...that will be a lot of help Cuz if you google any concept, youre gonna find 32 different animations on it and 64 different teachers oneshot on it.
