Items to Memorize
- Position-based coding (A=1, B=2... Z=26)
- Constant shift coding (+2, -3, etc.)
- Variable shift (+1, +2, +3... increasing)
- Reversal patterns (full word, pairs)
- Opposite letter coding (A↔Z, sum=27)
- Word-level coding (whole words swapped)
Mnemonic Tricks
How It Maps
| Cue | Maps To |
|---|---|
| POSITION | Each letter → its alphabet number (A=1, B=2... Z=26) |
| Constant SHIFT | Every letter moved forward/back by same amount (+2: A→C) |
| Variable SHIFT | Shift increases: +1 for 1st letter, +2 for 2nd, +3 for 3rd... |
| REVERSE | Whole word reversed, or alternate pairs swapped |
| OPPOSITE | A↔Z, B↔Y, C↔X (positions sum to 27) |
Why It Sticks
99% of banking exam coding-decoding uses just these patterns or their combinations. Checking in this order catches them fast.
Frequently Asked Questions
What if none of the three patterns work?
Check for opposite letters (A↔Z, sum=27), vowel/consonant replacement, or word-level coding (whole words swapped rather than letters).
How to handle number-letter mixed codes?
Numbers usually represent vowel positions (A=1, E=5, I=9, O=15, U=21) or just the alphabet position of that letter.
