Detailed CSIR NET Earth Science Exam Pattern 2026 (Section-Wise)

The CSIR NET Earth Science query paper is split into three distinct parts: Part A, Part B, and Part C. Each component has a selected objective, query depend, and staining protocol.

Part A: General Aptitude (The Common Ground)

Part A is common to all CSIR NET subjects, but for CSIR NET Earth Science aspirants, it’s far a rank booster.

• Total Questions: 20
• Questions to Attempt: 15
• Marks in keeping with Question: 2 Marks
• Total Weightage: 30 Marks
• Syllabus: Logical Reasoning, Graphical Analysis, Numerical Ability, Series Formation, and General Science.

Insight: Many Earth Science students come from a natural geology history and shy away from math. However, within the CSIR NET Earth Science examination 2026, Part A is incredibly slight. Scoring 20+ marks here eases the pressure at the subject-unique sections.

Part B: The Fundamentals (Subject Core)

This phase exams your breadth of know-how. It covers the basic ideas of Earth Sciences.

• Total Questions: 50
• Questions to Attempt: 35
• Marks in line with Question: 2 Marks
• Total Weightage: 70 Marks
• Nature of Questions: Direct, reminiscence-primarily based, and conceptual. Topics variety from Geomorphology and Climatology to basic Mineralogy.

Insight: In CSIR NET Earth Science, Part B requires pace. You have 50 questions, and you want to discover the 35 which you are a hundred% positive approximately. There is little room for calculation here; you both know the solution, otherwise you don’t.

Part C: The Analytical Challenge (The Game Changer)

This is the most important section of the CSIR NET Earth Science exam. It tests high-order questioning talents and the application of scientific concepts.

You can bypass whole devices (e.G., pass all Oceanography questions if you are a Geologist) and still attempt the most required questions. However, Part C contains a heavy penalty for mistakes, which we will talk inside the marking scheme section.

CSIR NET Earth Science Marking Scheme & Negative Marking

Understanding the marking scheme is critical due to the fact the CSIR NET Earth Science examination has a completely unique terrible marking penalty in Part C as compared to other topics like Life Sciences or Physical Sciences.

The Penalty Structure

The NTA imposes poor marking to deter random guessing. In the CSIR NET Earth Science paper, the penalty is proportional to the marks of the query.

SectionMarks according to Correct AnswerNegative Marking in keeping with Wrong AnswerDeduction PercentagePart A+2-zero.525%Part B+2-zero.525%Part C+4-1.3233%

Critical Analysis:

In Parts A and B, in case you wager 4 questions and get one right, you wreck even (more or less). However, in Part C of the CSIR NET Earth Science exam, the penalty is 33%.

• One correct answer = +4 marks.
• One incorrect answer = -1.32 marks.
• Three wrong answers essentially wipe out the benefit from one accurate solution.

This makes Part C of the CSIR NET Earth Science exam a excessive stakes quarter. Accuracy is far greater crucial than the variety of attempts. You can’t afford to gamble in Part C.

Topic-Wise Weightage in CSIR NET Earth Science 2026

The CSIR NET Earth Science syllabus is extensive. To navigate the exam pattern effectively, you ought to recognise which subjects appear in which. In 2026, the fashion has shifted slightly toward weather sciences and implemented geology.

Topics for Part B (Core Concepts)

Part B of the CSIR NET Earth Science examination generally covers:

• The Earth and the Solar System: Origins, Kepler’s legal guidelines, Earth’s orbital parameters.
• Earth Materials: Basic Mineralogy, Petrology, and structural geology principles.
• Surface Features and Processes: Geomorphology, weathering, erosion.
• Oceans and Atmosphere: Basics of atmospheric shape and ocean composition.
• Environmental Earth Sciences: Natural risks, pollutants, and ecology.

The CSIR NET Earth Science pattern ensures that Part B questions are spread calmly throughout those devices, forcing applicants to have a “Generalist” understanding of the planet.

Topics for Part C (Specialized Domains)

Part C permits for specialization. The eighty questions on this section of the CSIR NET Earth Science paper are commonly clustered into:

• Geology: Stratigraphy, Paleontology, Economic Geology, Tectonics.
• Physical Geography/Geophysics: Seismology, Gravity, Magnetism, Signal Processing.
• Meteorology: Climatology, Atmospheric Physics, Weather dynamics.
• Oceanography: Physical and Chemical Oceanography, Marine Geology.

Since you only need to reply 25 questions inside the CSIR NET Earth Science Part C, you could recognition deeply on simply  of those clusters (e.G., Geology + Geophysics) and forget about the relaxation.

Strategic Approach to the 2026 Exam Pattern

How do you address 150 questions in one hundred eighty minutes? The CSIR NET Earth Science exam is a race against time and choice fatigue. Here is a strategy tailor-made for the 2026 pattern.

The “Scan and Select” Technique

In the CSIR NET Earth Science exam, analyzing 80 questions in Part C takes time.

• Step 1: Spend the first 10-15 minutes scanning Part C. Mark questions that fall into your “Strong Zone” (e.G., if you love Petrology, mark all Petrology questions).
• Step 2: Ignore questions which might be prolonged or unexpected right away. Do not waste time analyzing them fully.
• Step three: The purpose is to locate the “easiest 25” questions. In CSIR NET Earth Science, an clean question includes the identical four marks as a difficult one. Don’t be a hero; be clever.

Time Allocation Strategy

• Part A: 30 Minutes. (Don’t exceed this. If you can not solve a puzzle, circulate on).
• Part B: 50 Minutes. (These are real. Quick selection making is wanted).
• Part C: 100 Minutes. (This is in which the CSIR NET Earth Science rank is determined. Calculate carefully, check gadgets, and keep away from the -1.32 lure).

The Role of Computer-Based Test (CBT) Features

Since the CSIR NET Earth Science examination 2026 is a CBT, you need to utilize the interface features:

• Mark for Review: Use this liberally. If you’re 50-50 on an option in Part B, mark it. In Part C, avoid guessing even in case you are 50-50 due to the high penalty.
• Question Palette: Use the palette to leap to your favourite sections. In CSIR NET Earth Science, Part C usually corporations questions by way of subject (Geology questions together, Meteorology collectively). Find your organization and persist with it.
• Timer: Keep a watch at the countdown. The CSIR NET Earth Science paper is prolonged. Don’t permit Part A consume into Part C’s time.

Cut-Off Trends for CSIR NET Earth Science

Understanding the exam sample is incomplete with out knowing the target score. The CSIR NET Earth Science cut-offs vary based on paper issue, however the pattern permits for excessive scoring.

• JRF Cut-Off (General): Historically tiers between one hundred ten – 120 Marks (fifty five% – 60%).
• LS Cut-Off (General): Ranges among a hundred – one hundred ten Marks.

To acquire 120 marks in CSIR NET Earth Science 2026:

• Part A: Target 20 Marks (10 correct questions).
• Part B: Target 40 Marks (20 accurate questions).
• Part C: Target 60 Marks (15 accurate questions).
• Total: one hundred twenty Marks.

Notice that you only want 15 correct solutions in Part C (out of 25 attempts and 80 options) to be in the secure zone. The CSIR NET Earth Science pattern is beneficiant if you keep accuracy.

Why Part C is the “Kingmaker” in CSIR NET Earth Science

We can’t stress this enough: Part C defines your bring about CSIR NET Earth Science.

• It contains 50% of the full marks (one hundred out of two hundred).
• It lets in the highest flexibility (Choice of 25 out of 80).
• It checks intensity.

In 2026, the NTA has added greater graphical and records-interpretation questions in Part C of the CSIR NET Earth Science paper. You is probably given a seismograph analyzing or a weather version graph and asked to interpret it. These questions are frequently easier than theoretical ones in case you recognize the basic standards, as the solution is hidden in the information itself.

Common Mistakes to Avoid in CSIR NET Earth Science Pattern

Even first-rate students fail the CSIR NET Earth Science examination due to the fact they misunderstand the sample.

• Over-Attempting in Part C: You can’t get credit score for extra than 25 questions. The machine will handiest evaluate the first 25 tried questions. If you answer 30, the remaining 5 are not noted, although they may be correct. In CSIR NET Earth Science, you must delete solutions to more questions to make certain your first-rate 25 are graded.
• Ignoring Part A: Many Earth Science students assume they are able to clear the cutoff using most effective Parts B and C. This is unstable. Part A is the “bonus” that pushes you from LS to JRF within the CSIR NET Earth Science advantage listing.
• Getting Stuck on Physics/Maths: Geophysics questions in CSIR NET Earth Science may be calculation-heavy. If you are not sturdy in Math, pass them. You have lots of theoretical Geology options to pick out from.
