Just tested with new sim and he was able to ask about school and was told his classroom number. I cheated him to have money to buy the lot, saved him to library, and started new game in same neighborhood as principal.
On the sim that is grade A student, she could ask about school and get classroom number when she was living in a different world. I was playing her for 2 in game weeks before the hsy pack released. She was in the werewolf's world and I sent her to school from there. After that I started new game with her (saved her to library) and moved her into the same neighborhood as the principal. That's when she couldn't ask about school after meeting the principal during the welcome wagon.
