Step-by-Step Preparation Strategy for IIT JAM Geology 2026

Step 1: Understand the Complete Syllabus

The first step is to analyze the official IIT JAM Geology syllabus, which includes the following major topics:

1. The Planet Earth – Origin, structure, and composition of Earth

2. Geomorphology – Landforms, processes, and mapping

3. Structural Geology – Folds, faults, joints, and stress-strain analysis

4. Paleontology – Fossils, evolution, and stratigraphic principles

5. Stratigraphy – Indian Stratigraphy, Geological time scale

6. Mineralogy – Properties, structure, and classification of minerals

7. Petrology – Igneous, sedimentary, and metamorphic rocks

8. Economic Geology – Ore genesis, mineral resources

9. Applied Geology – Remote sensing, engineering geology, groundwater

10. Geophysics and Basic Physics

11. Mathematics and General Aptitude

Download the official syllabus and divide it into weekly targets.

Step 2: Build a Strong Conceptual Foundation

You should begin by building concepts instead of jumping into problem-solving. Refer to standard textbooks used in universities for B.Sc. Geology.

Recommended Books:

Principles of Physical Geology – Arthur Holmes

Structural Geology – Billings or Ramsay

Sedimentary Petrology – Maurice Tucker

Petrology – Tyrrell or Winter

Paleontology – Ravindra Kumar

Economic Geology – Craig and Vaughan

Indian Stratigraphy – Krishnan

Remote Sensing and GIS – Lillesand and Kiefer

For General Aptitude:

Quantitative Aptitude – R.S. Aggarwal

Step 3: Create a Realistic Study Plan

You need a study plan that balances your strengths, weaknesses, and college schedule (if you’re still studying). Here’s a suggested 6-month study plan:

Months 1–2: Foundation Building

Cover basic concepts of Geomorphology, Mineralogy, and Structural Geology

Solve simple MCQs daily to strengthen basics

Months 3–4: Intermediate Topics

Dive into Petrology, Paleontology, and Stratigraphy

Start solving NATs and previous year papers

Months 5–6: Advanced Preparation

Focus on Economic Geology, Applied Geology, Geophysics

Revise thoroughly and attempt mock tests

Analyze mistakes and improve speed

Step 4: Solve Previous Year Question Papers

One of the most effective ways to boost your preparation is solving IIT JAM Geology previous year papers. It helps you:

Understand the question style

Learn time management

Identify important topics

Practice real exam difficulty

Try solving at least the last 10 years’ papers and analyze your accuracy.

Step 5: Attempt Mock Tests and Practice Papers

Enrolling in a test series helps simulate the real exam environment. Mock tests also help you identify and rectify weak areas.

While choosing mock tests, ensure they provide:

Section-wise analysis

Time-based performance

Solution keys with explanations

National percentile comparison

Step 6: Make Notes and Revise Regularly

Making short notes and flashcards helps in fast-track revision. Focus on:

Geological time scale

Mineral and rock identification tables

Structural formulas

Fossil examples and their characteristics

Economic minerals and their properties

Create a revision timetable during the final month to go through all topics at least twice.

Step 7: Focus on Numerical and Conceptual Problems

Sections like Structural Geology and Geophysics involve numericals. Practice problems related to:

Dip and strike calculations

Borehole problems

Seismic wave propagation

Map-based questions

Use graph sheets and geological maps to enhance your problem-solving techniques.

Step 8: Strengthen General Aptitude and Mathematics

The General Aptitude section is easy-scoring but often ignored. Practice regularly:

Logical reasoning

Data interpretation

Basic arithmetic

Probability and statistics

Geometry and mensuration

Spending just 15–20 minutes daily can help you secure 10+ marks easily in this section.
