NTSE has many questions based on the English Alphabet. These involve picking an odd one out, finding analogies and alphabet series. Solving these questions means just thinking about the English Alphabet in an objective manner.
When solving such questions, always keep handy the alphabet sequence (in natural and reverse order) and their position below it on a piece of paper. Described below are some important patterns seen among questions from this topic in NTSE.
These are mentioned in the decreasing order of their importance.
Jumping in Natural OrderLetters appear in the natural order but some letters are skipped in between. e.g. ACE, natural order sequence skipping 1 letter in between.
The number of letters skipped have its own pattern. e.g. 2 each, 3 each or 1, 2, 3 ...(i.e. increasing natural numbers) or 1, 3, 5, 7... (i.e. increasing odd numbers)
1. ADG 2. HKN 3. RUX 4. EFG
O one out is EFG
Jumping in Reverse OrderThis is same as above only skipping happens in reverse order. i.e. ECA, skips 1 letter in reverse order.
Sometimes some common letters are placed and the above mentioned pattern is seen around those. e.g.
JOPK, BOPC, QOPR
RepititionsIn the given sequence of letters, some letters repeat themselves and that is a distinguishing pattern.
SSTU, MMNO, AABC, KLMN
Odd one out is KLMN
Here for all others the first two letters are repeating and the following is a sequence of consecutive letters.
MiscellaneousVowels and Consonents - Letter series can be made of vowels and consonents arranged in a certain pattern. e.g. first letter is a vowel followed by three consecutive letters, or a group contains one consonent and two repeating vowels.
Letter Patterns - Letters can be defined by their pattern. e.g. Between CS, EV, OU only EV is formed by straight lines. Between TVL, FEH, KCW only KCW has one letter that is curved
