GATE 2027 shift analysis will follow the examination. For preparation now, the official 2026 CS1 key gives a concrete reference: 28 MCQs, 24 MSQs and 13 NATs. The question mix and reported CSE difficulty are kept separate below.

GATE 2027 Paper Analysis: What Is Available?

GATE 2027 has not been held. Its examinations are scheduled for 6, 7, 13, 14, 20 and 21 February. A shift-wise 2027 difficulty rating or good-attempt range would therefore be speculative. The detailed evidence below examines the official 2026 CS1 key and a separately labelled CSE difficulty report.

GATE 2026 CS1: Question-type Analysis

The counts come from all 65 entries in the official CS1 key. General Aptitude contributed 15 marks; the CS portion contributed 85. These are one paper's historical counts, not a fixed MCQ/MSQ/NAT ratio for 2027.

Reported Difficulty of GATE 2026 CSE

The report described algorithms and compiler design as particularly demanding in the first shift, and highlighted Boolean algebra, graph theory and LL(1) parsing among the second shift's challenging MSQs. These are reported impressions of those examinations, not a chapter forecast or an official ranking of subject difficulty.

What the Key Shows About Marking Risk

In CS1 2026, 57 marks came from MSQ and NAT questions: 35 from MSQ and 22 from NAT. They had no negative marking, but an MSQ still required the exact set of correct options. The remaining 43 marks were in MCQs with the applicable one-third penalty for a wrong answer.

A raw percentage of questions attempted ignores these differences. Record both the question marks and type when analysing an attempt using dated GATE papers.

Chapter Weightage and 2027 Preparation

The official key identifies type, section, answer and marks; it does not label every CS question by chapter. A defensible chapter-weightage table needs question-by-question classification and must handle questions spanning two topics without double counting. This page does not turn a provider's broad topic list into official chapter percentages.

Use the current CSE syllabus for coverage and the mock-test guide for complete timed practice. A historical shift impression cannot establish the 2027 cutoff, normalisation adjustment or rank at a given mark.
