Examinations Commiitee-ACS Spring Testing Program The testing program of the Examinations Committee-ACS continues a. high level of activity. Fifteen of the seventeen suhcommittees are currently engaged in writing new tests. The 1972 spring program features new tests in Inorganic Chemistry, Biochemistry, and Advanced High School Chemistry. In addition, a scrambled version of General Chemistry Form 1970 is now available and Form 1972 of the Graduate Level Placement Test in Physical Chemistry will he released July 1. In all, the 1972 program offers 40 examinations in high school chemistry, college placement, undergraduate college, and graduate level plscement.

Imnolganie Chemistry Form 197%: This 115-min examination has been written under the chairmantnship of Mike J . Sienko of Cornell University. The test consists of two parts. Part I has 60 ohjec tive items and Part I1 consists of five structured essav auestions.
ments and compounds. The structured essay questions cover structure, bonding, thermodynamics, coordination chemistry, and synthesis. Biochemistry Form 197b: This 90-min emmination was developed under the leadership of Eugene H. Cordes of Indiana. University. The test consists of 83 objective questions which focus on the areas of macromoleculitr chemistry, intermediary metabolism, biosynthesis of macromolecules, and biochemical synthesis. Advanced High School Chemisby Form 1978ADV: This 80-min examination was constructed under the leadership of Gerard A. Kass of Northport High School (N. Y.) and Joseph C. Maurer of Lyndenhurst High School (N. Y.). The test consists of 60 items in two parts. Part I of the test includes 40 questions in areas such as electrons in atoms, chemical bond, thermodynamics, kinetics, acid-hue chemistry, redox and electrochemistry, and chemical periodicity. Part I1 of the test consists of 20 quantitative problems on stoichiometry, kinetics, thermochemistry, redox, solutions, molecular and aqueous equilibria. The examination is intended for honors or advanced courses in high school chemistry and may also he used for college placement. Gradwle Level Placement in Physical Chemistry Form 197s-P: This 120-min examination is being completed under the leadership of Richard M. Noyes of the University of Oregon and Robert L. Scott of the University of California at Los Angeles.
