Luckily I had a teacher that thought it was bullshit we had to memorize the whole table and "forgot" to cover the wall-sized poster of the periodic table during the exam
Yeah I'm vaguely remembering something similar. I have these faint whispers of a memory of my teacher forgetting (or probably, "forgetting") to cover something on the wall during a memorization test.
Most chem PhDs don't even know the whole thing lol. We had to memorize just the symbols in high school, but positions weren't required. In my grad-level inorg course, the first test was a blank table that we had to fill in, but even then the f-block and transactinides were not required.
