Commonly asked questions
GATE papers have three major sections; General Aptitude, Engineering Mathematics & Specific Subject. There are 65 questions asked for 100 marks in GATE exam.
General aptitude questions are asked for 15 marks, Engineering mathematics in some paper codes, 13 marks and the rest 72 marks from the chosen subject.
In some paper codes engineering mathematics will be excluded only 15 marks general aptitude questions and rest 85 marks will be of chosen subject.
According to topper's and experts, the ideal number of questions to attempt correctly is 50 to 55, to obtain a GATE rank under 1000.
Yes, GATE has negative marking for Multiple Choice Questions (MCQs) only. In GATE question paper, MCQs will be of one and two marks. Hence, the marking scheme for such questions can be checked below -
- For one mark MCQ - 1/3rd mark will be deducted
- For two mark MCQ - 2/3rd mark will be deducted
Considering the past year's trends and experts analysis, GATE CSE, ECE, and EE papers are considered as the toughest papers in GATE exam. Here's why -
Complex technical concepts and fundamentals
Heavy mathematics
Branch popularity and number of registered candidates are more.
GATE 2026 ECE Exam Date
GATE exam dates for all 30 test papers is now available. The exam took place in two shifts: forenoon (9:30 am to 12:30 pm) and afternoon (2:30 pm to 5:30 pm). GATE 2026 ECE exam was scheduled for February 15 in the first shift. Candidates appearing for exam must download GATE admit card for ECE before the exam date. The credentials required to download hall ticket are enrollment ID and password.
In addition, students must also go through GATE exam day guidelines and GATE dress code before reaching the exam centre.
