CSE-PPT Professional cheat sheet

Synonym: word with the same or nearly the same meaning in context; check the sentence for clues.

Antonym: word with opposite meaning; look for contrast signals like 'but', 'however', 'although'.

Analogy: identify the relationship (e.g., part-to-whole, cause-effect, degree) and apply to the answer pair.

Sentence completion: use context clues and grammatical agreement (number, tense) to eliminate choices.

Grammar: subject-verb agreement-singular subject takes singular verb; ignore intervening phrases.

Pronoun reference: a pronoun must agree with its antecedent in number and gender.

Diction: choose the word that fits the intended meaning and tone; avoid colloquialisms in formal writing.

Reading comprehension: main idea is often in the first or last sentence; details support it.

Logical organization: paragraphs should have a clear topic sentence, supporting details, and a concluding sentence.

Percent change = ((new − old) / old) × 100; increase if positive, decrease if negative.

Simple interest = principal × rate × time; rate as decimal, time in years.

Compound interest = P(1 + r/n)^(nt) − P; n = compounding periods per year.

Average (mean) = sum of terms / number of terms; median = middle value when ordered.

Ratio a:b means a/b; to divide a quantity in ratio a:b, parts = total/(a+b).

Work rate: if A does a job in x hours, rate = 1/x job per hour; combined rate = sum of rates.

Distance = rate × time; for opposite directions, add speeds; same direction, subtract.

Area of triangle = ½ × base × height; circle area = πr²; circumference = 2πr.

Probability = favorable outcomes / total outcomes; independent events: multiply probabilities.

Syllogism: use Venn diagrams; 'all A are B' means A is subset of B; 'some A are B' means intersection non-empty.

Valid argument: conclusion must follow necessarily from premises; check for fallacy of affirming the consequent.

Logic: contrapositive of 'if P then Q' is 'if not Q then not P' (logically equivalent).

Seating arrangement: draw positions; use clues like 'left of', 'between', 'opposite' to fix order.

Blood relations: map family tree; use gender and generation to determine relationship.

Number series: look for differences, ratios, squares, primes, or alternating patterns.

Coding-decoding: identify shift (e.g., +1, +2) or reversal; apply consistently.

Data sufficiency: determine if given statements are enough to answer; no need to compute exact value.

Assumption: unstated premise necessary for argument; identify gap between evidence and conclusion.

Alphabetical order: compare letter by letter; if first letters same, move to second, etc.

Filing: names are usually filed last name first, then first name, then middle initial.

Spelling: common errors-'ie' vs 'ei' (i before e except after c), double consonants, silent letters.

Proofreading: check for typographical errors, missing words, incorrect punctuation, and consistency.

Date format: in formal records, use 'Month Day, Year' (e.g., January 1, 2025).

Numerical filing: arrange numbers in ascending order; treat as whole numbers, not digit by digit.

Abbreviations: standard ones (e.g., Mr., Dr., etc.) are filed as written; ignore punctuation.

Cross-referencing: use 'see' or 'see also' to link related files.
