I can understand your reason for saying this, (useful things often sell well) but a market only validates that people are willing to pay for something, not that it is ‘valid’ empirically.
I understand it’s simple, especially the addition questions. But it’s been a long time since I’ve had to do long division. Without knowing some of the questions on this test beforehand, I’m confident I would be toast.
And I believe the public system is divided further still by region. Near-north district school board, Toronto district school board, etc. (Though I’m unsure how much autonomy each board has.)
Reading this was a “you read my mind” experience. Feels good to hear someone consider the same problems and come to similar conclusions. I’ve been daydreaming of building some append-only search-first note taking app for a while, love the insights here!
