SAT II/ SAT 2 Chemistry Preparation Books

Purpose of the Sat II Chemistry Test

Measure understanding of chemistry at a level  suitable for college preparation, independent of the  particular textbook used or instructional approach.

Format  of the Sat II Chemistry Test

-85 multiple-choice questions

-Approximately five questions on equation balancing and/or predicting products of chemical reactions, which are distributed among the various content categories.

Questions cover topics emphasized in most high school courses. Because of course differences, most students will find that there are some questions on topics with which they are not familiar.

Questions may require you to

-recall and understand the major concepts of chemistry and to apply the principles to solve specific problems in chemistry.

-organize and interpret results obtained by observation and experimentation and to draw conclusions or make inferences from experimental data, including data presented in graphic and/or tabular form.

On this Subject Test:

-a periodic table indicating the atomic numbers and masses of elements is provided for all test administrations.

-problem solving requires simple numerical calculations.

-the metric system of units is used.

NOTE: Calculator use is not permitted.

Recommended Preparation for the Sat II Chemistry Test

-One-year introductory chemistry course at the college-preparatory level

-Laboratory experience, which is a significant factor in developing reasoning and problem-solving skills and should help in test preparation even though laboratory skills can be tested only in a limited way in   a multiple-choice test

-Mathematics preparation that enables handling simple algebraic relationships and applying these to solving word problems

-Familiarity with the concepts of ratio and direct and inverse proportions, exponents, and scientific notation
