high school student June Baker and her teacher Darrin Rassmusen huddled over blueprints trying to figure out what went wrong with a drywall installation. Turns out it was confusion over two panels both labelled A. "We have one wall A that's right and then one that's not built because I had to take it apart," Baker said. "But I've learned from my mistake and they realized from that mistake that they need to start labelling each wall with numbers."
