ACS Cooperative Examinations
Four new tests were published by the Examinations Committee in 1970: General Chemistry Form 1970, Quantitative Analysis Form 1970, Advanced High School Chemistry Form 1970ADV, Graduate Level Placement in Inorganic Chemistry Form 1970-1. Although data for Quantitative Analysis Form 1970 are still being collected, the norms for the other 1970 tests are presented. I n addilion, the n o r m for Qualitative Andysis Form 1969 and Physical Chemistry Form 1969 also appear. The condensed norms presented here areseleoted froma. larger body of data, which may be obtained from Examinations Committee-ACS, University of South Florida, Tamps, Fla. 33620,. Condensed norms for other currently used American Chemical Society Cooperative 37, 166 Examinations have been published in THIS JOURNAL, (1960); 38, 211 (1961); 39, 151 (1962); 40, 144 (1963); 41, 166 (1964); 42, 170 (1965); 43, 217 (1966); 44, 243 (1967); 45, 273 (1968); 46, 182 (1969); 47, 321 (1970).

Juniors (63%), seniors (33%), and graduate students (4%) composed the group. The lecture hours were 3.0 per week in each case and laboratory hours range from 0 to 6 per week with a mean of 3.2.
Graduate Level Placement in Organic Chemistry A new Graduate Level Plscement Examination in Organic Chemistry Form 1971-0 will be relessed by the Examinations Committee of the Division of Chemical Education of the American Chemical Society in July, 1971. The examination containing seventy multiple-chbice cp&tions, has been prepared by a subcommittee consistin. of E. L. Eliel (chairman). University of Notre Dame; H. L. &rey, Oregon Graduate center for ~ t u d y and Research; J. E. Baldwin, Univemity of Oregon; M. Gates, University of Rochester; P. J. Hawkins, Oberlin College; 11. G. Hiskey, University of NorthCarolina; E. S. Huyser, University of Kansas; H. G. Kuivils, New York State University (Albany). The purpose of the examination is to test the undergraduate prepamtion in organic chemistry of students entering graduate schools in chemistry. A Large number of graduate depsrtments offering the PbD degree use the examination for purposes of graduate placement. Previous Graduste Level Placement Examinations in Organic Chemistry were prepared in 1961, 1965, and 1968 by committees under the chairmanship first of J. F. Bunnett (Brawn University) and then of E. L. Eliel. The new examination differs from its
