1 Syllabus

Aligned to the official UPSC CSE notification. Always re-check the latest PDF on UPSC exam syllabus.

• Comprehension.
• Interpersonal skills including communication skills.
• Logical reasoning and analytical ability.
• Decision-making and problem-solving.
• General mental ability.
• Basic numeracy (Class X level).
• Data interpretation (charts, graphs, tables, data sufficiency) — Class X level.

2 Previous year questions (PYQs)

Solve official CSAT papers year-wise. Theme clusters:

• Reading comprehension (often the largest time sink).
• Quant: percentages, ratios, time-work, number system (Class X).
• Reasoning: syllogism, seating, puzzles (as asked that year).
• Data interpretation sets.

Official papers:

• CSAT PYQ PDFs
• Download PYQ hub
• CSAT coaching (Delhi)

3 Resources

• Official PYQs first — they are the syllabus in practice.
• Class X NCERT maths for weak arithmetic.
• One reasoning workbook, not five apps.
• Ahuja Sir’s warning in the seminar recap: do not ignore CSAT until two weeks before Prelims.

4 Strategy

• Diagnostic: one full recent CSAT paper in exam conditions.
• Weekly: 2 RC sets + 20 quant + 15 reasoning. Protect this slot.
• In the hall: accuracy first; 33% is the floor.
• Do not start new tricks in the last week; revise an error notebook.

5 Common mistakes

• Opening CSAT two weeks before Prelims.
• Spending 40 minutes on one DI set.
• Guessing wildly in RC (negative marking).
• Treating CSAT as “only for engineers” — it is Class X plus reading.

6 Answer-writing example

Worked approach (CSAT is MCQ, not Mains writing): A comprehension paragraph asks the author’s main point vs a supporting example.
