Department chairmen emphasized different motives yesterday for establish-accelerated programs for qualified students.

H. Westheimer, chairman of the Department of Chemistry, stressed the preparation of entering students as the basic reason for offering advanced for freshmen. But Richard D. Brauer, chairman of the Department of stated that preparedness was less than high aptitude and interest.

Westheimer and Brauer agreed was "very difficult" to distinguish background from higher and noted that both were used as for placement in accelerated .

Westheimer said that Chemistry 11, with Chemistry 12, covers three in two, was offered for the first this year for students who had received a firm grounding in , physics, and calculus in high . The 25 students with the highest scores were chosen for the from the 50 to 60 with the background, Westheimer said.

explained that freshmen with high school preparation through might take either the in-history Mathematics 1 or the accelerated Mathematics 11. The difference lies the course catalogue terms " high mathematical aptitude and strong interest in theoretical mathematics."
