UPSC CSAT 2026: 10 Common Mistakes Candidates Must Avoid

UPSC Civil Services Aptitude Test (CSAT) 2026 will be held on May 24, 2026. This paper often presents a significant hurdle for UPSC aspirants. While focus typically remains on General Studies, CSAT can become a major challenge if not approached strategically.

With approximately 100 days remaining, a serious and effective strategy is crucial for success, even for those beginning their preparation. Read here 10 common mistakes UPSC CSAT aspirants make and how to avoid them to maximize your score.

Why Does CSAT Matters?

The Civil Services Aptitude Test (CSAT) can be a deciding factor for UPSC aspirants. It comprises three main sections:

1. Quantitative Aptitude (Quant)
2. Reasoning
3. Reading Comprehension (RC)

While it is a qualifying paper, scoring above the cutoff is mandatory to move forward, making it a critical hurdle.

10 Common Mistakes Candidates Must Avoid for UPSC CSAT 2026

Here are the most frequent errors UPSC CSAT aspirants make, along with e practical solutions to overcome them for a higher score.

Mistake 1: Skipping an Entire Section

Completely ignoring one section is a major risk. UPSC frequently changes difficulty levels year to year:

• Example: For instance, Quant was challenging in 2023, while Reading Comprehension posed difficulties in 2024.
• Risk: Relying on only one strong section can prevent you from clearing the qualifying cutoff.

Correct Approach: Cover all three sections. Skip complex sub-topics if needed, but don’t abandon an entire section.

Mistake 2: Ignoring Your Current Level

Your strengths and weaknesses vary. A one-size-fits-all plan may leave gaps in preparation or overemphasize easy areas.

Solution: Tailor your study plan according to performance in mocks:

Mistake 3: Poor Time Management

Getting stuck on difficult questions and wasting time, leaving easier questions unanswered.

Solution:

Use the 3-Round Strategy to avoid getting stuck on difficult questions and missing easier ones. Categorize questions as you encounter them:

1. Round 1 (R1): Questions solvable with high accuracy in 30 to 50 seconds. These are typically easy, formula-based, or from mastered topics. The first goal is to scan the entire paper and solve all R1 questions.
2. Round 2 (R2): Questions you are confident in solving, but which require more time (e.g., 2.5 to 3 minutes). Mark these for a second pass.
3. Round 3 (R3): Very difficult, time-consuming (>3 minutes), or topics you are weak in. Attempt these last, only if time permits.

This categorization must be done within 5-10 seconds of reading a question. Consistent practice and mock tests develop this ability.

Remember;

“Your selection is not stopped because you couldn’t solve tough questions. It’s stopped because you either skipped or incorrectly answered easy or moderate questions.”

Therefore, ensure you correctly identify and solve all easy (R1) and moderate (R2) questions.

Mistake 4: Not Simulating Real Exam Conditions

Students practice in calm conditions, but face the actual exam in the afternoon (2:30-4:30 PM) after GS, leading to underperformance.

Solution: Always take full-length mock tests in the 2:30 PM to 4:30 PM slot to simulate exam conditions, training your brain to perform under fatigue and pressure.

Mistake 5: Failing to Solve Unfamiliar Questions

Another mistake is understanding concepts but struggling to apply them independently.

• The Reason: Insufficient independent practice; mind untrained for self-reliant problem-solving.
• The Solution: After understanding a concept, you must solve practice problems (like PW ONLYIAS DPPs), PYQs, and questions from a book on your own to build problem-solving skills

Mistake 6: Getting Stuck in Reading Comprehension (RC)

Many aspirants struggle with anxiety when tackling RC passages due to lack practice in the section.

Why It’s a Mistake:

Fear reduces accuracy and speed, making it harder to achieve the 66-mark qualifying cutoff.

The Solution: Overcome fear by practicing the last 10 years of PYQs for RC. Analyze UPSC answer keys for logic. This builds confidence to answer ~80% correctly, sufficient for the 66-mark cutoff. Aim to clear threshold, not perfect score.

Mistake 7: Relying Only on One Section

Focusing solely on one section, such as RC, and neglecting others like Quant is another mistake that you should avoid. If your chosen section becomes unexpectedly difficult, you risk failing the qualifying cutoff.

Solution:

Prepare all sections. Focus on high-yield Quant topics (Number System, Percentage, Average) to provide a safety net.

Mistake 8: Ignoring Mock Tests

Many aspirants use mocks only for scoring rather than practice.

Why It’s a Mistake: Without strategic use, you miss opportunities to improve time management, accuracy, and exam strategy.

Solution: Use mocks to implement the 3-Round Strategy, simulate exam conditions, and refine speed and accuracy.

Mistake 9: Not Prioritizing High-Yield Topics

Identify topics that consistently appear in PYQs. Strategic effort allocation demands understanding each section’s weightage and typical difficulty.

Mistake 10: Lack of Systematic Revision

Remember that knowledge fades without reinforcement, reducing accuracy and confidence during the exam.

Solution:

Revise daily or weekly. Keep formulas, shortcuts, and previous mistakes handy for quick revision sessions.

Final Tip: Remember the Three Pillars of CSAT Success

Success in CSAT hinges on a systematic approach:
