Take this test and prove you are prepared for the next chemistry exam you need to take.

Passing chemistry exams is easier with adequate preparation that involves taking practice tests or quizzes before taking the exam.

The quizzes below are to test your knowledge of the topic: properties of chemical substances, mixtures and compounds and methods of separation them, calculation of empirical formulas, calculations involving atomic masses, calculations involving gas laws, kinetic theory of gases, and atomic theory.

This test is suitable for one preparing for any of the following examinations: University Matriculation Exams (UME), Post UME, PCE, SSCE, NECO, GCE, Cambridge O/L and IGCSE; and other standardized exams that seek to assess students' proficiency in ordinary and intermediate level chemistry courses, including SAT II,
AP, and state proficiency exams.

You are advised to simulate actual examination conditions when taking this test to derive maximum benefits from it, which include building your confidence, metal alertness, and speed, which are needed for success in examinations and quiz competitions.

A time duration of 9mins to complete all ten questions is suggested to help you build the speed you need to be able to complete all question when taking the real examination.
