Alphabet Memorization Frameworks: EJOTY and Reverse Pairs
The biggest time-waster in Reasoning is writing out the alphabet A-Z on your rough sheet before the exam starts. You must know letter positions automatically.
- EJOTY: E(5), J(10), O(15), T(20), Y(25).
- C-FILORUX: Table of 3 multiples: C(3), F(6), I(9), L(12), O(15), R(18), U(21), X(24).
- Reverse Pairs (Sum = 27): A-Z (Azad), B-Y (Boy), C-X (Crux), D-W (Dew), E-V (Evening), F-U (Fun), G-T (GT Road), H-S (High School), I-R (Indian Railway), J-Q (Jungle Queen), K-P (Kurta Pajama), L-O (Love), M-N (Man).
Knowing reverse letter pairs by heart solves 40% of recent SSC coding-decoding questions instantly.
The 4 Main Coding Archetypes
1. Direct Positional Shift (+3, -2, alternating prime shifts).
2. Cross Pattern (First letter codes to last, second to second-last).
3. Reverse Opposite Letter Coding (Letter replaced by its reverse pair equivalent).
4. Vowel-Consonant Segregation (Vowels shifted by +1, Consonants coded by positional rank).
Number Series: Difference of Differences
When an integer sequence appears irregular, take consecutive differences. If the first difference reveals no pattern, take the second difference. Over 70% of complex SSC series reduce to a constant arithmetic difference at the second tier.
