About Graduate Aptitude Test in Engineering — Chemical Engineering (GATE CH) 2027
The Graduate Aptitude Test in Engineering — Chemical Engineering (GATE CH) is one of the most competitive entrance exams, conducted by the IIT Madras (organising institute for GATE 2027). Preparing for the GATE CH requires systematic practice, conceptual clarity, and regular self-evaluation. Our platform offers dynamic mock tests, previous years' resolved papers, and AI-enabled analysis to help you secure a top rank.
Frequently Asked Questions
Which PSUs recruit through GATE CH 2027?
GATE CH is accepted by ONGC, GAIL, IOCL, HPCL, BPCL, RCFL, NFL, and FACT. Oil and gas and fertiliser PSUs actively recruit Chemical Engineers through GATE scores.
What are high-weightage subjects in GATE CH?
Mass Transfer, Heat Transfer, Chemical Reaction Engineering, and Fluid Mechanics together account for 40-50 marks in GATE CH. These are the four most important subjects to master.
Is GATE CH accepted at IIT Bombay for MTech?
Yes, IIT Bombay has one of the best Chemical Engineering departments in India. GATE CH qualifiers need a score above 700 and rank within top 50-100 for IIT Bombay MTech admission.
How many students appear for GATE CH annually?
GATE CH has approximately 15,000-20,000 applicants per year, making it less competitive than GATE CS or GATE ME. This means even a moderate GATE CH score can yield a decent rank for NIT admissions.
What is the scope of GATE CH for government jobs?
Chemical Engineering PSUs offer excellent packages. ONGC and IOCL engineer trainees earn ₹60,000-₹80,000 per month. GAIL and BPCL also offer competitive CTC of ₹15-25 LPA with benefits.
What is the GATE CH qualifying cutoff?
General category qualifying marks: 25 (2026), 27.7 (2025) and 25 (2024). The qualifying bar is modest; PSU (IOCL, GAIL, ONGC) shortlists demand scores above 650 instead.
How should I start preparing for this GATE paper?
Begin with the official syllabus — GATE questions rarely go outside it. Then work subject-wise with previous year questions (10+ years), and finish with 8-10 full-length CBT mocks. Remember: General Aptitude (15 marks) and Engineering Mathematics (13 marks) are common to every candidate — 28 of your 100 marks come before the core subject even starts.
How to Prepare for GATE CH
Fluid Mechanics and Heat Transfer are the most predictable GATE CH subjects — solve 10 years of previous questions
Chemical Reaction Engineering (CRE) requires deep conceptual understanding of reactor design equations
Process Control (PID Controllers, Laplace Transforms) overlaps with EE knowledge — thorough preparation pays off
Thermodynamics for Chemical Engineers uses different notation than Mechanical — pay attention to sign conventions
Mass transfer and reaction engineering numericals share design-equation logic — learn them as one framework
Chemical technology and plant economics are pure-recall marks — one consolidated notes sheet is enough to bank them
