This document provides a table of specification for a chemistry paper 1 exam from 2017. It lists 50 questions that could appear on the exam grouped into categories of knowledge, comprehension, and application. For each question, it provides the topic, question type, and whether it includes a diagram or table. This allows examiners to structure the exam to test students on different cognitive levels and topics in chemistry while adhering to the specification.
