GATE

The GATE exam follows a well-defined structure and pattern. Exam Format: GATE is conducted online as a Computer Based Test. The exam duration is 3 hours .Question Paper Structure: The GATE question paper consists of three sections:General Aptitude (GA)Engineering Mathematics (EM)Subject SpecificQuestion Types: Multiple Choice Questions (MCQs),  Multiple Select Questions (MSQs) (Some papers) and Numerical Answer Type (NAT) Marking Scheme: Marks awarded for each question type (one-mark, two-mark) are specified beforehand. The specific deduction for each wrong answer is mentioned in the exam brochure. There's no negative marking for unattempted questions or MSQs. 

GATE is conducted every year by one of the IITs. In 2025, GATE is being conducted by the Indian Institute of Technology  (IIT), Roorkee. It will be conducted in various cities across the country.  The GATE 2025 exam pattern has been released. There are no major changes in the exam pattern from last year. It describes the basic structure of the question paper and contains details including the number of questions, marks, duration, etc. The question paper will comprise Multiple-choice (MCQ), Multiple Select (MSQ), and Numerical Answer Type NAT questions. Negative marking is there for multiple-choice questions, but for numerical answers, there will be no negative marking.  For more details, candidates can check: https://www.shiksha.com/engineering/gate-exam-pattern.
