The GATE 2026 Chemical Engineering exam checks three things more than anything else — clarity of concepts, accuracy in calculations, and logical application of theory. With increasing competition for PSU jobs, M.Tech seats in IITs/NITs, and research fellowships, scoring 70+ marks has now become the golden target for most aspirants.
The good news? 70+ is 100% achievable if you follow the right plan, consistency, and practice approach.
This blog shares proven preparation strategies that toppers have used to score high in GATE CH year after year.

1. Study Smart Based on Weightage
Don’t jump randomly between topics — prepare according to past year exam weightage.
🔥 High-weightage subjects (must master)
| Subject | Approx. Marks |
|---|---|
| Chemical Reaction Engineering | 10–12 |
| Mass Transfer | 8–12 |
| Thermodynamics | 8–10 |
| Heat Transfer | 8–10 |
| Fluid Mechanics | 6–8 |
| Process Calculations | 6-8 |
| Engineering mathematics | 14–15 |
👉 Moderate subjects
• Mechanical Operations
• Process Control & Instrumentation
• Chemical Technology
General Aptitude (GA) = Free 12–15 Marks
With regular practice, scoring 10+ here is very common.
👉2. Concepts First — Formulas Later
In GATE, mugging formulas doesn’t work. You score only when concepts + application are strong.
Examples from toppers’ approach:
- In CRE, focus on kinetics, selectivity & rate laws — not just reactor formulas
- In Mass Transfer, understand resistance & driving force
- In Thermodynamics, master fugacity, activity & partial molar properties
👉 Concept clarity + logic = marks in GATE
3. Practice Numericals in Bulk
To score big, you must solve big.
Spend 60–70% of your preparation time on numericals:
- Previous 20–25 Years GATE Questions
- Chapter-wise numerical sets
- GATE Sample Papers
- Full-length & subject-wise mock tests
Because 70–80% of GATE Chemical Engineering is numerically driven — solving more = scoring more
4. Improve Calculation Accuracy
Even a small jump in calculation skills can boost 6–10 extra marks.
✔ Use scientific calculator shortcuts
✔ Track units & dimensions properly
✔ Avoid exponent / log mistakes
✔ Keep a personal notebook for formulas & assumptions
5. Take the Right Test Series — And Analyze
A good test series can convert 50-marks students → 70+ scorers.
Many toppers prefer Eii GATE Online Test Series because:
✔ Questions match real GATE difficulty & pattern
✔ Exam interface feels exactly like the real GATE screen
✔ Helps train time-management & numerical decision-making
✔ Every year, multiple questions in GATE match from Eii Test Papers almost exactly
After every test, analyze:
- Weak chapters
- Repeated mistakes
- Slow calculation areas
If marks dip — do not panic.
