GATE CE Pattern FAQs

Paper and Sections

Is GATE 2027 a 100-mark or 100-question paper?+

It is a 100-mark paper with 65 questions: 10 General Aptitude and 55 subject questions. Questions carry either one or two marks.

Is the whole paper online?+

Yes. GATE is a computer-based examination in English. Numerical answers are entered through the on-screen virtual keypad.

Can I change my optional subject during the examination?+

There is no optional subject block in this paper. The syllabus defines what can be tested; it does not offer a choice to replace one subject with another. Leaving a question unanswered earns zero, but it does not reduce the set of topics that may appear.

Marking and Results

Does selecting one correct MSQ option give partial credit?+

No. You must select exactly all the correct options. A partial set or a set containing an incorrect option earns zero.

Is there negative marking for numerical questions?+

No. An incorrect NAT receives zero. The negative-marking rules apply to MCQs only.

Can I multiply my marks by ten to calculate my GATE score?+

No. The score formula uses the General-category qualifying mark and a top-candidate benchmark for the paper. Multi-session papers use normalised marks first. A simple marks-times-ten calculation does not reproduce the official score.

Will the 2027 chapter distribution match last year?+

The official section allocation applies, but there is no promise of the same chapter-by-chapter distribution. Use dated paper analysis as a record of that examination, not as a guarantee for the next one.

*The article might have information for the previous academic years, please refer the official website of the exam.
