How do you get to be a member of the sims.net registers for school children and a timetable of lesson pupils??

You need to talk to the individual who is igned as the SIMS adminitrator at the school where you work, who is usually an admin t. I ume you work at a school, otherwise you will not be permitted SIMS access, because it contains a vast amount of confdential information that only school and LEA workers are allowed to access.
