CSIR NET July 2026 Chemical Sciences: Last 45 Days Strategy to Maximise Your Score

The final 45 days before the CSIR NET July 2026 Chemical Sciences exam can significantly impact your final score. At this stage, success depends less on learning new topics and more on revising effectively, solving Previous Year Questions (PYQs), and improving accuracy in topics you have already prepared.

With the right strategy, candidates can maximise their score, avoid common preparation mistakes, and improve their chances of securing JRF. Explore the exam structure, safe score targets, subject-wise priorities, and a practical 45-day preparation plan.

Understanding the CSIR NET Exam Structure

Before planning your study and revision schedule, it is important to understand how marks are distributed across different sections of the exam. This helps you allocate time more effectively and focus on areas with the highest scoring potential. 

The total potential marks for the entire paper (including optional questions) are 360. However, candidates are required to attempt questions worth a maximum of 200 marks.

Target Score & Cut-off:

Historically, an average score of 115-120 marks is considered a safe score for securing JRF and a good rank. This means you need to obtain approximately 120 marks out of the 360 total potential marks (or 200 marks that can be attempted).

Strategic Approach to Scoring

The exam offers considerable flexibility through optional questions. Several questions are intentionally challenging and can be skipped strategically. 

• Emphasis: If a question appears from a topic you have studied, you must be able to solve it correctly.

• Chemistry Marks: Excluding aptitude, the Chemistry section accounts for 320 marks, from which you need to secure 120+ marks.

• Aptitude (Part A): Even if unprepared, attempting 3-5 aptitude questions correctly can provide bonus marks, helping to clear the JRF cut-off and improve rank.

Achieving the Target Score: An Example

Consider the following scenario to comfortably achieve 120+ marks:

• Part C: Instead of 25, attempt 15 questions correctly (15 x 4 = 60 marks).

• Part B: Instead of 35, attempt 25-30 questions correctly (25 x 2 = 50 marks, or 30 x 2 = 60 marks).

• Part A: Attempt 4-5 aptitude questions correctly (4 x 2 = 8 marks, or 5 x 2 = 10 marks).

This combination can lead to 120+ marks. The core message is to focus on the prepared topics:

• Do not be discouraged by chapters you haven't covered.

• Instead, revisit and master the chapters you have studied.

• For each mastered chapter:

• Practice questions thoroughly.

• Review formulas and concepts.

• Create short notes.

• Crucially, if a question appears from a topic you have prepared, you must be able to solve it correctly.

• It is acceptable to skip questions from unstudied chapters as the exam provides sufficient optionality. However, for prepared topics, accuracy and certainty are paramount.

Subject-Wise Scoring Potential

If the 320 marks for Chemistry were equally divided among the three main subjects (Physical, Inorganic, Organic), each would roughly contribute 106 marks.

• Single Subject Strategy: Relying solely on one subject (e.g., Physical Chemistry for 106 marks) to clear the 100-105 General cut-off is very difficult. Achieving a perfect score in one subject is highly improbable.

• Combining Two Subjects Strategy: A more viable approach is to combine strengths from at least two subjects. For instance, strong performance in Organic and Physical Chemistry, or Organic and Inorganic Chemistry, is a viable path to achieving the target score. The more subjects you cover effectively, the higher your chances.

• Efficiency: In any chapter you prepare, aim for 100% efficiency and mastery.

Strategic Subject Combination Example

Even with less-than-perfect scores in each subject, combining strengths can yield a high total:

• Physical Chemistry: Securing 60 marks out of 106 (approx. 50% efficiency).

• Inorganic Chemistry: Securing 60 marks out of 106 (approx. 50% efficiency).

• Organic Chemistry: Securing 20 marks (even if only selectively prepared).

This scenario results in a total of 140 marks (60+60+20), which is a strong score potentially leading to an excellent rank.

Importance of Chapter Weightage:

Candidates should calmly study and maintain a mental "calculation" of how much weight each chapter contributes. This understanding helps in prioritising and building a personalised list of topics based on their expected marks.

Strategy to Prioritise Topics

1. Create a Personalised Topic List:

• On an A4 sheet, list all chapters you have previously studied across Physical, Organic, and Inorganic Chemistry.

• Filter these topics into two categories:

• Well-mastered: Chapters you are very confident in.

• Challenging: Chapters you struggle with.

2. Develop a Strategic Approach:

• For well-mastered chapters, aim for further refinement and perfection.

• For challenging chapters, bring them to a reasonable level of understanding and competence.

• Personalisation: This list and strategy must be personalised; what works for one student may not work for another.

The Role of Previous Year Questions

The best method to determine if a chapter is well-mastered or challenging is through Previous Year Questions (PYQs):

• Mastered Chapter: You can consistently solve PYQs from that chapter.

• Challenging Chapter: You struggle with PYQs, making errors or facing difficulties. This indicates a need for improvement.

• Focus: Work on what you know. Do not get bogged down by chapters you haven't mastered; instead, focus on strengthening what you have prepared.

High-Scoring Chapters in Physical Chemistry

Physical Chemistry contributes significantly to the overall score. Focusing on the most frequently asked and high-weightage chapters can improve scoring efficiency. 

• Quantum Chemistry: Contributes 25-30 marks. Even if not fully comfortable, try to cover segments you understand. Do not completely abandon it.

• Mandatory Chapters: The following topics must be covered as they consistently yield marks:

• Chemical Kinetics

• Electrochemistry

• Group Theory

• Thermodynamics

• Spectroscopy

• Solid State

• Statistical Thermodynamics

These chapters are guaranteed to provide marks. If Quantum Chemistry is skipped, it becomes even more crucial to master these other topics. Certain topics consistently appear in Part C, contributing 4 marks each, making a block of 16-20 marks. These are fixed topics from which questions are guaranteed.

High-Scoring Chapters in Inorganic Chemistry

The following are the most important and high-scoring topics in Inorganic Chemistry, which should be prioritised:

• Coordination Chemistry

• Organometallic Chemistry (OMC)

• Inorganic Spectra

• Bio-Inorganic Chemistry

• F-Block Elements

Additionally, topics like Bonding and Main Group Chemistry may have occasional questions.

High-Scoring Chapters in Organic Chemistry

• For students struggling with Organic Chemistry:
  Focus on these relatively separate topics:

• Pericyclic Reactions

• Photochemistry

• Organic Spectroscopy

• Stereochemistry (can be studied separately)

• For students strong in Organic Chemistry:
  Understand the interconnected pattern of these core topics:

• General Organic Chemistry (GOC)

• Stereochemistry

• Reaction Mechanism (combining GOC and Stereochemistry principles)

• Reagents

• Name Reactions (as application parts)

These five core topics should be studied in a combined and integrated pattern.

Daily Study Plan & Key Don'ts

A sample daily study schedule may include:

• 5–6 hours of focused theory revision

• 2–3 hours of PYQ practice

• 1 hour of revision and formula review

• 30–40 MCQs for concept reinforcement

Candidates should adjust the schedule according to their preparation level and available study time.

Emphasis on PYQs:

If the theory segment is reduced, allocate more time to PYQs. Re-solve the same questions if needed; repetition helps solidify understanding.

What to AVOID during the last 45 days:

• Do NOT start new textbooks.

• Do NOT begin entirely fresh chapters. If you have a faint prior understanding of a chapter, you can refine it, but avoid completely new topics that you have no prior knowledge of.

• Do NOT focus solely on theory; prioritise question practice.

• Consider attending YouTube series specifically for practice questions.

Final Preparation Advice

Personalised Preparation:

• Create a personalised list of topics.

• Assign marks to each topic based on its weightage.

• Assess your confidence level for each topic ("I know this," "I don't know this").

• Base your preparation strategy on this self-assessment.

• Set weekly targets within the 45-day plan.
