Key points
- Position from the right = 27 minus position from the left
- EJOTY anchors: E 5, J 10, O 15, T 20, Y 25
- Opposite letters add up to 27, such as A and Z or M and N
- Above 26 subtract 26; below 1 add 26
- A pair that appears to move backwards signals wrap-around past Z
- The nth letter from the right is the (27 − n)th from the left

Positions in the alphabet
Every letter-series question becomes a number-series question once the letters are converted into their positions.
- From the left: A = 1, B = 2, up to Z = 26.
- From the right: position from the right = 27 minus the position from the left.
| Letter | A | B | C | D | E | F | G | H | I | J | K | L | M |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| From left | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| From right | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 |
| Letter | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| From left | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
| From right | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
Key point
Subtract from 27, not from 26. Using 26 shifts every answer by one position, and that wrong value always appears among the options.
The EJOTY shortcut
Memorise five anchors: E = 5, J = 10, O = 15, T = 20, Y = 25. Any letter can then be placed by counting a step or two from the nearest anchor, without running through the alphabet from A.
Example
R is two before T, so R = 20 − 2 = 18. W is two before Y, so W = 25 − 2 = 23.
Opposite letters
Two letters are opposite when their positions add up to 27.
The pairs are A–Z, B–Y, C–X, D–W, E–V, F–U, G–T, H–S, I–R, J–Q, K–P, L–O and M–N.
A memory aid runs through the words BY, DeW, FUn, HS and LOve, which cover five of the pairs.
Wrap-around
After Z the alphabet starts again at A. If a calculated position goes above 26, subtract 26. If it falls below 1, add 26.
Example
W is 23, and W + 5 = 28. Since 28 − 26 = 2, the answer is B. A pair that seems to move backwards, such as W to B, is the signal that wrap-around is involved.
Position arithmetic
- The kth letter to the right of the mth letter from the left is the (m + k)th letter from the left.
- The kth letter to the left of the mth letter from the left is the (m − k)th letter from the left.
- The nth letter from the right is the (27 − n)th letter from the left.
Exam tip
Write EJOTY on the rough sheet the moment the paper starts. It removes almost every counting error in this topic.
