The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions.
General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. [1] The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out ...
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam.
The Chemistry Exam is divided into three parts: Part 1 includes 19 multiple-choice questions. Part 2 features two calculation tasks using chemical formulas, one task for constructing a reaction chain and composing an ionic (short) equation, and one redox reaction (OVR) task. Part 3 is experimental. The exam duration is 180 minutes. [10]
The ACS Division of Chemical Education provides standardized tests for various subfields of chemistry. [77] [78] The two most commonly used tests are the undergraduate-level tests for general and organic chemistry. Each of these tests consists of 70 multiple-choice questions, and gives students 110 minutes to complete the exam.
Multiple choice questions carried about 60% of the total weightage and were the crucial determinant for selection to the next stage. The present format (from 2014-15 onwards) is composed entirely of 60 multiple-choice questions in physics, chemistry and biology.
