This is the downside of eliminating redundancy and over-centralizing! What a disaster.

I was fortunate enough to finish school before they introduced the whole every child must have a laptop thing. So much centralised data for no reason.

Also fortunately, my kids are homeschooled.

Great. Collegeboard shared my info without my consent. Anything I can do?
