Condensed Norms: ACS Cooperative Examinations Five new tests were released by the Examinations Committee in 1968: Organic Chemistry Form 1968, Brief Physical Chemistry Form 1968B, Biochemistry Form 1968, Advanced High School Chemistry Form 1968ADV, and Graduate Placement Examination in Organic Chemistry Farm 19680. The condensed norms presented here are selected from s. larger body of data. which may be obtained from the Examinations Committee, American Chemical Society, Theo. A. Ashford, Chairman, University of South Florida, Tampa, Florida 33620. Data for norms for the 1967 form of Brief Organic Chemistry are presented. Data for norms for Brief Physical Chemistry Form 1968B are still being collected.
