GATE is a Computer Based Test (CBT) of 3 hours duration consisting of 65 questions for a total of 100 marks. The paper includes three types of questions: Multiple Choice Questions (MCQ), Multiple Select Questions (MSQ), and Numerical Answer Type (NAT) questions. For MCQs, there is negative marking: 1/3 mark is deducted for a wrong 1-mark question, and 2/3 mark is deducted for a wrong 2-mark question. There is NO negative marking for MSQ and NAT questions. The paper is divided into General Aptitude (15 marks) and Core Subject (85 marks), though most engineering papers also include Engineering Mathematics as a compulsory part of the 85 marks.
