Frequently Asked Questions

The Chemistry Regents consists of a series of multiple-choice, constructed-response, and extended constructed-response questions that cover a variety of topics across 12 major subject areas.
Your school will determine when exactly you should take the Chemistry Regents. The test is administered in January, June, and August of every year.

The Chemistry Regents is divided into three parts that test-takers will have three hours to complete. This exam contains 85 questions in total.

Part A: Multiple Choice
A multiple-choice question offers four possible answers from which you choose the one that best answers the question or completes the statement. This part of the exam consists of 30 content-based questions that assess your knowledge and understanding of core material and represents approximately 35 percent of the examination.

Part B-1: Multiple Choice
This section of Part B consists of multiple-choice questions as described in Part A. These questions are content- and skills-based and designed to assess your ability to apply, analyze, and evaluate material. This part of the exam contains 20 questions.

Part B-2: Constructed Response
In a constructed-response question, there is no list of choices from which to choose an answer; rather, you are required to provide the answer. Constructed-response questions test skills that include performing numerical calculations, drawing and interpreting graphs, making particle diagrams, and applying core concepts to solve short-answer problems. This part of the exam contains 15 questions. The combined sections of Part B account for 30 percent of the examination.

Part C: Extended Constructed Response
Part C consists of content-based and application questions that assess your ability to apply knowledge of scientific concepts and skills to address real-world situations. Be sure to write clear, complete sentences while using your knowledge of chemistry to answer these questions. This part of the exam contains 20 questions and represents approximately 20 percent of the examination.

All the questions on the Chemistry Regents will test major understandings, skills, and real-world applications drawn from the following 12 skill and subject areas:

M. Math Skills
R. Reading Skills
I. Atomic Concepts
II. Periodic Table
III. Moles/Stoichiometry
IV. Chemical Bonding
