GATE AG Prep Portal provides all 1,324 official GATE AG previous year questions spanning 2007 through 2026. Every question includes detailed step-by-step mathematical derivations, official answer keys, KaTeX formula formatting, and subject-wise categorization.

How many full-length CBT mock tests are provided on the GATE AG portal?

The portal includes 50 full-length CBT mock tests specially crafted according to the official GATE AG 65-question / 100-mark blueprint with TCS-iON palette states, in addition to 20 official past exam papers from 2007 to 2026.

What core subjects are covered in the GATE Agricultural Engineering syllabus?

The official syllabus encompasses 5 major sections: Farm Power and Machinery (AG-FM), Soil and Water Conservation Engineering (AG-SW), Agricultural Processing and Food Engineering (AG-AP), Engineering Mathematics (AG-EM), and General Aptitude (AG-GA), spanning 181 specific subtopics.

Is GATE AG Prep Portal free to use and available offline?

Yes, GATE AG Prep Portal is 100% free with zero fees. It is built as an offline-first Progressive Web App (PWA) with service worker caching and local IndexedDB data persistence, allowing aspirants to practice tests and revise formulas anywhere without an active internet connection.

What are the qualifying cutoff marks for GATE Agricultural Engineering (AG) across categories?

Historical GATE Agricultural Engineering qualifying cutoff marks typically range between 25.0 to 29.5 marks for General/Unreserved, 22.5 to 26.5 marks for OBC-NCL and EWS, and 16.5 to 19.5 marks for SC, ST, and PwD categories out of 100 total marks. Scoring 60+ marks generally secures an All India Rank (AIR) in the top 30, qualifying for M.Tech admissions at premier institutes like IIT Kharagpur and ICAR postgraduate scholarships.

Is a virtual scientific calculator allowed in the GATE AG CBT exam?

Yes. Physical handheld calculators are strictly prohibited in the official GATE examination. Candidates must use the onscreen official TCS-iON virtual scientific calculator provided in the test interface. The GATE AG Prep Portal features an exact interactive replica of this official TCS-iON virtual calculator across all CBT mock tests and practice modes.

What is the chapter-wise subject weightage in GATE Agricultural Engineering?

Based on 14-year trend analysis across official GATE AG papers, the approximate marks weightage is: Farm Power and Machinery (~25-28%), Soil and Water Conservation Engineering (~25-28%), Agricultural Processing and Food Engineering (~22-25%), Engineering Mathematics (13%), and General Aptitude (15%). The portal's built-in Syllabus Tracker breaks down weightages across all 181 subtopics.

Can I crack GATE Agricultural Engineering with self-study without coaching?

Yes, absolutely. The GATE AG syllabus is formula-driven and standard reference books (Michael & Ojha, Sahay, Toledo) combined with rigorous solving of 1,324 official PYQs (2007-2026) provide complete preparation.

Which subject has the highest weightage in GATE Agricultural Engineering?
