Two of the several thousand students who began flocking back to District No. 40 schools Tuesday are Marcia Colvin, 9, and Greg Mardock, 9, fourth graders at Memorial School. School officials are expecting enrollment in district schools to exceed last year's figure by a considerable margin. The registration process, which started the day after Labor Day, continued into Wednesday at some of the schools.
