General aptitude questions Each subject's test contains 10 questions that test the "general aptitude" (language and analytic skills), apart from the core subject of the discipline. Duration and examination typeThe GATE examination consists of a single test of 3-hour duration that contains a total of 65 questions, worth a maximum of 100 marks. The questions consist of both multiple choice questions (MCQs) and numerical answer type questions. Numerical answer type questions does not contain any options for the answers, the candidate has to solve the numerical and write the answer in the spec given. From 2014 onward, the examination for all the papers is carried out in an online Computer Based Test (CBT) mode where the candidates are shown the questions in a random sequence on a computer screen. The candidates are required to either select the answer (for multiple-choice question type) or enter the answer for numerical answer type question using a mouse on a virtual keyboard (keyboard of the computer is disabled). Candidates are provided with blank paper sheets for rough work and these have to be returned after the examination. At the end of the 3-hour window, the computer automatically closes the screen from further actions.
