The integrated reasoning is relatively new section on the GMAT (introduced from 5th June, 2012). One of the essays is replaced by the integrated reasoning section. As the name suggests, it involves some type of reasoning to answer the question. It includes analysis of some data which will be given in the question.
The IR section presents you with 12 questions, one question at a time, and you have 30 minutes to answer them. To get credit for answering a question correctly, you have to answer all its parts correctly. You don’t receive partial credit for getting one part of the question correct. Unlike the verbal and quantitative reasoning sections, the IR section isn’t computer adaptive.
Four types of questions are used in the Integrated Reasoning section:
You are presented with a sortable table of information, similar to a spreadsheet, which has to be analyzed to find whether answer statements are accurate. This is a three-part IR question, where you use the data to make judgments about three pieces of information; each of your judgments has to be correct to get credit for the question.
You are asked to interpret a graph or graphical image, and select the option from a drop-down list to make response statements accurate. Graphs can be bar graphs, pie charts or venn diagrams.
The questions are accompanied by two to three sources of information presented on tabbed pages. You have to click on the tabs and examine all the relevant information, which may be a combination of text, charts, and tables, to answer questions.
A question will involve two components for a solution. Based on a short written explanation of a phenomenon, situation, or mathematical problem, you come up with the proper assertions or mathematical expressions that meet the two interrelated criteria presented in the question.
