In the last nine years, we have designed, implement, and evaluated the systemic approach to teaching and learning chemistry (SATLC)(1-4). II n continuation of this work, we design a new shape of objective tests based on systemics. Objective tests require a student to choose or provide a response to a question whose correct answer is pre- determined, such question might require a student to select a solution from a set of choices [MCQs], True / Falls (TFQs); Matching (MQs). Traditional objective test are very good instrument examining recall of information and application of terms but cannot assess learning beyond comprehension. Systemic objective tests can challenge students and test higher learning levels (Analysis, Synthesis and Evaluation).
3
There are several types of systemic questions. We will illustrate in this issue SMCQs as an example of systemic objective test. MCQs are the traditional choosing one from a list of possible answers. (SMCQs) are choose of one systemic from a list of possible systemics. Each systemic represents three, four, or five,……physical, or chemical relations. Various types of SMCQs from general, organic, heterocyclic and physical, chemistry will be illustrated.

Keywords: SMCQ's, SATLC By using (SMCQ's), we expect from students:: - Making maximum connections between chemistry concepts, atoms, compounds, and reactions. - Recognize which cognitive level they should view the chemistry material. - See the pattern rather than the parts.
