GATE AR 2026 — Paper analysis

The GATE Architecture & Planning (AR) 2026 paper, conducted on 15 February by IIT Guwahati, maintained the restructured 81-question format introduced in recent years. With a total of 100 marks spread across General Aptitude (15 marks), a common Part A (55 marks), and an optional Part B (30 marks — either B1 Architecture or B2 Planning), the paper tested a wide spectrum of competencies. This analysis breaks down topic weightage, difficulty trends, and strategic takeaways for future aspirants.

Key Observations

Planning frameworks dominated Part A. Questions on Ekistics, Perry’s Neighbourhood Unit, SDGs, ODF++ protocols, PMAY-U 2.0, and Kevin Lynch’s concepts collectively accounted for nearly a quarter of the paper. This continues the trend of GATE AR heavily weighting statutory and conceptual planning knowledge. The URDPFI matching question (Q75) and the zoning classification question (Q73) in Part B2 were particularly well-crafted, requiring candidates to distinguish between form-based, Euclidean, inclusionary, and performance zoning — a nuance that rewards deep reading over surface-level memorisation.

Housing standards and building codes were the heaviest single topic. NBC 2016 appeared in multiple questions — fire resistance of service ducts (Q14), glass type classification (Q59), and parapet wall detailing (Q61). The Pritzker Prize question (Q39) tested contemporary awareness (Liu Jiakun, 2025 laureate), while the Islamic architecture MSQ (Q53) required distinguishing “Mimar” (architect) from “Minaret” (tower), a classic trap. The construction technology questions on suspension bridges (Q36), operation theatre zoning (Q37), and AutoCAD shortcuts (Q38) made Part A’s MSQ section particularly demanding.

Numerical questions favoured formula recall over computational complexity. The 14 NAT questions in Part A were largely straightforward applications of standard formulas: volume division for masonry (Q24), ECS calculation (Q25), declining balance depreciation (Q26), residential density conversion (Q28), Manning’s equation (Q45), and FAR addition (Q48). The PERT scheduling question (Q46) required careful calendar mapping with a holiday, making it the most error-prone NAT. The water demand projection (Q43) combined geometric population growth with per-capita demand — a two-step process where rounding at intermediate stages could push the answer outside the accepted range.

Part B1 (Architecture) was calculation-intensive. Six out of sixteen B1 questions were NATs, covering ventilation rate (Q55), footing design (Q56), heat gain through glazing (Q62), beam analysis (Q63), illumination level (Q64), and Building Energy Index (Q65). The heat gain question (Q62) stood out as the most multi-step, requiring candidates to first derive SHGC from the LSG ratio and VLT, then separately compute conductive and radiative gains before summing. The BEI question (Q65) tested whether candidates could reverse-calculate total energy from the solar percentage share.

Part B2 (Planning) balanced policy knowledge with quantitative reasoning. The TOD policy radius question (Q66), DEM data type (Q67), and Gini coefficient formula (Q68) were direct hits from the standard syllabus. The transport engineering section included Greenshield’s jam density (Q71), Dijkstra’s shortest path (Q80), and V/C ratio with PCU conversion (Q81) — all classic GATE-style numericals. The NPV calculation (Q78) and demand elasticity (Q79) tested core economics. Notably, the fiscal deficit question (Q72) required careful reading of the Consolidated Funds table to separate debt from non-debt receipts — a skill that rewards practice with Union Budget-style data.

The official answer key for Q77 (passive remote sensing) lists A and C (Sonar and Aerial photos), which has generated discussion since Sonar is conventionally classified as an active technique. Candidates should note that passive sonar (listening without emitting) exists in naval contexts, and this may explain the official key’s inclusion. Verify with official sources if this affects your score.

Trends vs Prior Years

• The ratio of MSQ questions has steadily increased; GATE AR 2026 featured approximately 20 MSQs across Parts A and B, up from roughly 15 in 2024, making partial knowledge increasingly penalised.
• Matching-type MCQs (Q29–Q35, Q57–Q59, Q73–Q75) continue to be a staple format, with 5-item groups requiring precise recall — no partial credit is possible.
• NAT answer ranges have narrowed in some questions (e.g., Q25, Q48, Q56, Q64, Q71 with single-value ranges), suggesting the exam setters are becoming more precise in their model solutions.
• The inclusion of PMAY-U 2.0 (not 1.0) and the 2025 Pritzker laureate indicates that the paper incorporates very recent developments, so relying only on older editions of standard textbooks is risky.
• The weighted distribution across Part B1 and B2 remains balanced, with neither optional section significantly easier than the other — a deliberate design choice to maintain parity.

How to Use This Paper

Treat this paper as a full-length mock test under exam conditions: 3 hours, no breaks, negative marking on MCQs (−1/3 for 1-mark, −2/3 for 2-mark). After attempting, use the solutions file to identify not just what you got wrong but why — was it a conceptual gap, a calculation slip, or a misread question? For each incorrect answer, follow the course link to the relevant lesson for targeted revision.

Focus your next study cycle on the highest-yield areas: planning frameworks and housing standards together account for over 40 questions. Within these, NBC 2016 provisions, government schemes (PMAY, SBM, NAPCC), and urban design theory (Lynch, Perry, Howard) are near-guaranteed to appear every year. For numerical preparation, drill Manning’s equation, depreciation methods, FAR calculations, and population projection — these are formulaic and highly repeatable.
