Section 1: VARC (Verbal Ability & Reading Comprehension)

VARC Structure

Reading Comprehension Strategy

Types of RC Passages:

• Abstract/Philosophy
• Economics/Business
• Social Sciences
• Science/Technology
• History/Culture

Approach:

1. Skim first (1 minute)—get main idea, structure
2. Read questions before detailed reading
3. Read actively—mark key points mentally
4. Answer evidence-based—find support in passage
5. Skip if too difficult—manage time

Common RC Question Types:

Verbal Ability Strategy

Para Jumbles:

• Find the opening sentence (introduces topic, no pronouns)
• Find mandatory pairs (connected ideas)
• Use chronology and logical flow
• Eliminate options systematically

Para Summary:

• Read paragraph completely
• Identify main point (not details)
• Eliminate options with specific details
• Choose most comprehensive summary

Odd One Out:

• Find common theme in 4 sentences
• Identify the outlier (different scope or topic)

VARC Preparation Plan

Daily Practice:

• Read 2-3 editorials from quality newspapers
• Solve 2-3 RC passages
• Practice 5-10 VA questions
• Vocabulary building (10 words/day)

Recommended Sources:

Monthly Targets:

• Month 1-2: Build reading speed and habit
• Month 3-4: Focus on accuracy
• Month 5-6: Timed practice and mocks

Section 2: DILR (Data Interpretation & Logical Reasoning)

DILR Structure

Data Interpretation Strategy

Common DI Types:

• Tables
• Bar graphs
• Pie charts
• Line graphs
• Mixed/complex data sets

Approach:

1. Understand the data (2-3 minutes per set)
2. Identify relationships between data points
3. Calculate only what's asked—avoid over-calculation
4. Use approximations when possible
5. Look for patterns before calculating

Calculation Tips:

• Master percentage calculations mentally
• Learn fraction-to-percentage conversions
• Use approximation strategically
• Practice mental math daily

Logical Reasoning Strategy

Common LR Types:

Approach:

1. Read the entire set first
2. Identify what's fixed and what varies
3. Draw diagrams (essential for arrangements)
4. Make logical deductions step by step
5. Verify before finalizing

DILR Set Selection

In CAT, you won't solve all DILR sets. Choose wisely:

Easy Sets (Attempt First):

• Familiar topic/format
• Clearly presented data
• Calculations look straightforward
• Questions seem direct

Hard Sets (Attempt Later/Skip):

• Multiple unknowns
• Vague conditions
• Complex calculations
• Time-consuming

The 5-Minute Rule: Spend 5 minutes understanding a set. If no progress, move on.

DILR Preparation Plan

Daily Practice:

• Solve 2-3 DI sets
• Solve 2-3 LR puzzles
• Focus on set selection
• Time each set
