Topic-wise Revision Points

Verbal Reasoning

  • Syllogism rules (All, Some, No statements)
  • Blood relations coding (+, -, ×, ÷ for relationships)
  • Direction sense shortcuts (Pythagoras theorem for diagonal distances)
  • Coding-decoding patterns (Letter position, Opposite letters, Number coding)

Non-Verbal Reasoning

  • Series completion patterns (Rotation, Addition/Subtraction of elements)
  • Analogy relationships (Size, Shape, Number, Position, Rotation)
  • Classification (Odd one out based on multiple criteria)
  • Mirror and water image rules (Left-right reversal for mirror, upside-down for water)

Analytical Reasoning

  • Puzzle solving approach (Make table/grid, note positive/negative information)
  • Seating arrangement types (Linear, Circular, Rectangular, Mixed)
  • Blood relation tree construction
  • Direction-based puzzle shortcuts

Mathematical Reasoning

  • Number series patterns (Arithmetic, Geometric, Fibonacci, Prime)
  • Letter series (Position based, Skip pattern, Reverse order)
  • Missing number in matrix (Row/Column operations)
  • Clock angles formula: |30H - 5.5M| degrees

Memory Aids & Mnemonics

💡

Blood Relations: B for Brother, S for Sister, F for Father, M for Mother, + for 'of', - for ' '

💡

Directions: Never Eat Shredded Wheat (North, East, South, West clockwise)

💡

Syllogism: All → Some, No → No conversion possible

Important Formulas & Rules

Calendar: Day of week = (Date + Month code + Year code + Century code) mod 7

📐

Number of rectangles in n×m grid = n(n+1)/2 × m(m+1)/2

📐

Number of squares in n×n grid = n(n+1)(2n+1)/6

Revision Strategy

1

First Pass (30 minutes)

Quickly scan all topics. Identify areas where you feel less confident. Mark them for focused revision.

2

Deep Revision (60 minutes)

Study marked topics thoroughly. Write down key points. Create your own mnemonics for difficult concepts.

3

Practice (45 minutes)

Solve 10-15 questions from this category. Apply the formulas and techniques you just revised.

4

Final Review (15 minutes)

Go through mnemonics and formulas one more time. Note down any remaining doubts for later clarification.
