CSAT 3 Round Strategy:

Round 1: “Accuracy First” Round (30–40 minutes)

What to Attempt First:

• Reading Comprehension (RC) passageswith direct, factual questions.
• Basic reasoning puzzlesthat are easy & quick to solve.
• Mathematical questionsinvolving simple arithmetic (percentages, ratios, averages) if you’re confident.

Why This Works:

• These questions require less calculation& are accuracy-focused.
• Helps build momentum & saves time for tougher sections later.

Time Allocation:

• Spend around 35–40 minutes.
• Aim to attempt 25–30 questionswith high accuracy.

Round 2: “Logical Reasoning & Moderate Math” Round (40–90 minutes)

What to Attempt:

• Logical reasoning puzzlesinvolving arrangements, sequences, analytical reasoning.
• Moderate difficulty math topics like time-speed-distance, simple algebra, basic geometry.
• Decision making questionsthat require logical deduction.

Key Techniques:

• Break down complex puzzlesinto chunks that can be managed.
• Skip lengthy calculationson the first go: mark them for review if time-consuming.
• Use approximation techniqueswherever possible to save time.

Time Allocation:
