How is the Chemistry Regents set up?

The Chemistry Regents exam is divided into three parts with a three-hour time limit to complete.
Part A - Multiple-Choice
A multiple-choice question offers several answers from which you choose the one that best answers the question or completes the statement. This part of the exam has content-based questions assessing your knowledge and understanding of core material and represents approximately 35 percent of the examination.
Part B1 - 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. The combined sections of Part B (multiple-choice plus constructed-response) represent approximately 30 percent of the examination.
Part B2 - 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, and analyzing material. The combined sections of Part B represent approximately 30 percent of the examination.
Part C - Extended Constructed-Response
These are constructed-response questions that require more time and effort on your part to answer. Part C consists of content-based and application questions assessing your ability to apply knowledge of scientific concepts and skills. Be sure to write complete, clear sentences while using correct chemistry in your explanations. This part represents approximately 20 percent of the examination.
