Information retention and retrieval is a long solved problem in technology, you could pass a standardised test using technology in dozens of different ways, from a lookup table to Google searches.
The fact that LLMs can complete a standardised test is interesting because it’s a demonstration of what they can do but it has not one iota of impact on standardised testing! Standardised tests have been “broken” for decades, the tests and answers are often kept under lock and key because simply having access to the test in advance can make it trivial to pass. A standardised test is literally an arbitrary list of questions.
You’re arguing a completely different point.
