The bus is typically the easy part. If there are staggered start times for elementary, MS and HS, then the elementary kid just takes the MS bus and math is 1st period. Then they get shuttled back to their school. If there aren't a whole lot of kids in Algebra, then they could just use a school van. Heck, the district maintenance staff could drive them back. Won't help your kiddo now, but for future kids in the same situation, maybe worth a mention.
