GATE 2021 Question Paper PDFs

The 2021 archive includes Environmental Science and Engineering and Humanities and Social Sciences. XH is a paper family: Economics is one choice, not a name for the entire XH paper. Match the optional subject before using a key.

GATE 2021 Paper Structure and Marking

A paper with optional sections may print more questions than one candidate needs to attempt. For XE and XL, follow the section choices printed in that year's paper. Adding every optional section would create a total larger than the candidate's actual test.

For a numerical-answer question, enter the number in the form requested and use the accepted range in the key when one is specified. A value outside that range earns no marks. MCQ penalties apply only to wrong MCQs, not to blank answers. In an MSQ, selecting only some correct options earns no partial credit; adding an incorrect option also loses the marks for that question.

Checking Answers Against the Key

Match three details before marking: year, paper code and session. For subjects with more than one session, use the key for the same session as the paper. A master key follows the master paper's question order; when another copy uses a different order, match the question text and options.

• Mark MCQs by both their key and their 1-mark or 2-mark value.
• Use the numerical range printed in the NAT key rather than rounding every answer to the same number of decimals.
• For MSQs, compare the entire selected set with the key.
• Treat a worked solution as an explanation. If it conflicts with the final official key, keep the final key as the scoring reference.

Worked marking example: 12 correct 1-mark MCQs and 18 correct 2-mark MCQs earn 48 marks. Three wrong 1-mark MCQs deduct 1 mark, while three wrong 2-mark MCQs deduct 2 marks. These MCQs contribute 45 marks, before adding any correct numerical or multiple-select answers.

That total measures one paper attempt. It does not directly give a GATE score out of 1,000 or an All India Rank. The GATE exam pattern explains the current paper structure and marking distinctions.

Using the 2021 Paper for GATE Preparation

Attempt the branch paper and General Aptitude together when measuring a full-paper attempt. For topic revision, separate the questions by subject and type; a total mark alone will not show whether losses came from conceptual errors, numerical entries or incomplete multiple selections.

After marking, separate wrong answers, skipped questions and correct answers reached by guessing. For a wrong numerical answer, redo the units and intermediate calculation before reading the solution. For a wrong MCQ, identify the step that made the distractor look plausible. Reattempt those questions without the key, rather than counting a remembered answer as a fresh correct attempt.

Use the GATE question-paper collection for another year or session after reviewing this attempt. The GATE mock-test guide covers computer-based practice and the difference between short drills and complete paper attempts.

Topic frequency in a single paper is a description of that paper, not a guaranteed chapter-wise weightage for the next examination. Record the marks attached to the actual questions when comparing two papers; counting questions alone mixes 1-mark and 2-mark items.
