Past papers, year by year
Verified 15 Sept 2026 against the official sitePublished by IIT Guwahati as a public PDF. placd links to each year’s official paper and describes it — pattern, weightage, cutoffs — and never reproduces its text. The practise column is placd’s own set for that year: original questions assembled to the year’s distribution, scored the way the paper scores.

Frequently asked
- What does placd cover for GATE CH?
- Chemical Core, Process Design, Engineering Mathematics, Aptitude — the paper's sections, as practice banks with explanations and an AI tutor, plus a selection-board mock interview.
- Are GATE CH practice papers the real previous-year papers?
- No. placd's year-wise sets are original pattern sets authored to each year's real distribution — section split, question types, mark weighting and duration — with our own detailed solutions. Past-paper text is not reproduced.
- Where can I find GATE CH previous-year question papers?
- The year-by-year table above links each year's official paper where the conducting body publishes one (it does, as public PDFs), with the year's pattern, weightage and cutoff. placd never reproduces past-paper text.
- Where do I apply for GATE CH?
- Only on the conducting body's official site — placd links to it in the schedule section above and never hosts an application form. The dates and eligibility shown are read from that site and carry the date they were verified.
- How is a GATE CH practice set scored?
- As the exam scores it: negative marking of one-third of the marks for a wrong objective answer, no negative marking on MSQ or NAT.
