Series Completion

A question that gives a sequence of numbers, letters, or figures following a hidden rule and asks for the next or missing element. Common rules include constant differences, squares, cubes, and alternating patterns.

Related: Number Series, Coding-Decoding

A sequence of numerals governed by an arithmetic or algebraic pattern such as adding successive primes, multiplying by increasing integers, or combining two interleaved sequences. You infer the rule and supply the missing term.

Related: Series Completion, Arithmetic Progression
Coding-Decoding

A reasoning task where words or letters are replaced by a code according to a fixed rule, and you must either decode a given code or apply the rule to a new word. Rules may involve shifts, reversals, or position values.

Related: Letter-Number Position Value, Blood Relations
Blood Relations

Statement and Assumption

A critical-reasoning item where a short statement is followed by proposed assumptions, and you judge which assumption is implicit in the statement. The test is whether the statement could stand without that assumption.

Related: Statement and Conclusion, Syllogism

Related: Mirror and Water Image, Paper Folding and Cutting
Mirror and Water Image

A spatial task asking what a figure or word looks like reflected in a vertical mirror or in water. Left-right reverses in a mirror; up-down reverses in water, and letters with symmetry behave specially.

Paper Folding and Cutting

A figure-based question where a sheet is folded, punched or cut, then unfolded; you must predict the pattern of holes or cuts. Tracking symmetry axes of each fold is the reliable method.

Related: Compound Interest, Profit and Loss
Compound Interest

Interest that is added to the principal at fixed intervals so that later interest is earned on interest. It grows faster than simple interest, and half-yearly or quarterly compounding changes the effective rate.

Related: Antonym, One-word Substitution
Antonym

A word that expresses the opposite meaning of another word, such as 'scarce' for 'abundant'. Antonym questions require attention to the part of speech and the exact sense of the given word.

Related: Synonym, Idiom and Phrase

Error Spotting

A grammar item where a sentence is divided into parts and you must identify the part containing a grammatical error, or declare the sentence error-free. Common errors are subject-verb agreement and wrong prepositions.

Related: Subject-Verb Agreement, Active and Passive Voice
Subject-Verb Agreement

The rule that a verb must match its subject in number and person, so singular subjects take singular verbs. Collective nouns, indefinite pronouns, and intervening phrases are frequent traps.

Related: Error Spotting, Active and Passive Voice
Active and Passive Voice

Two ways of presenting a clause: active voice makes the doer the subject, while passive voice makes the receiver the subject. Conversion questions test tense handling and pronoun changes.

Related: Direct and Indirect Speech, Error Spotting

A passage followed by questions on its main idea, details, tone, or implied meaning. Answers must be supported by the text, so option elimination and locating evidence are the key skills.

Related: Synonym, Inference
Inference

A conclusion drawn from evidence in a passage rather than stated directly. Comprehension questions on inference ask what the author implies, so the answer must be strongly supported but not explicitly written.

Related: Reading Comprehension
Cloze Test

A passage with blanks, each to be filled by the most suitable word from the options. It tests grammar, collocation, and the ability to follow the passage's logic.
