Techniques: Subjects

Quant - PS and DS

  • Integers – consecutive, prime, odd/even, positive/negative/zero, ascending/descending order

  • Absolute Values – absolute values and inequalities, conditions for addition/subtraction of absolute variables, square root of a variable

  • Summation – summation equations for specific arithmetic series, mean and median 

  • Quadratics – quadratics for speed calculations, roots of quadratics, graphical interpretations

  • Factors – divisibility, LCM, GCF, prime factorization, no. of factors

  • Remainder – remainder form, remainder and decimal, remainder and arithmetic series

  • Factorials – factorial properties, prime factorization of factorials, factorial and prime

  • Geometry – perimeter, area, surface area, volume, ratio of area and volume, triangle, circle, cube

  • Overlapping – two groups, three groups, overlaps of two groups or EXACTLY two groups, neither group

  • Standard Deviation – scaling of SD, SD and outliers, min-SD theorem, SD of population, SD of binary variables of equal population

  • Combinatorics – order, duplication, order fallacy, binary, special properties of nCr and nPr, scenarios of coins, passwords, cards, balls, dice, teams, polygons

  • Probability – duplication, right use of “1-P” method, symmetricity, conditional probability, non-mutually exclusive probability

Verbal - SC

  • Trivium Rule – Grammar, Logic, Style

  • Subject-verb Agreement – subjective clause, subject position, modifier

  • Parallelism – verb, noun, modifier, fake parallelism

  • Idioms – 30 common idioms and pitfalls

  • Pronouns – singular, plural, ambiguity, “this”

  • Verb – tense, transitive/intransitive

  • Noun – singular/plural, countable/uncountable, collective noun, "v-ing" as noun

  • Comparison – like-to-like comparison in nature and plurality, key words of comparison

  • Subjunctive Mood – five “wish verbs”, impossible assumption

  • Sentence Structure – subject-verb-object, nominative absolute, "comma + v-ing"

  • Special Rules – such as, whether, rather than, because, although, being, able

  • Style – active, verb, short, no redundancy

Verbal - CR

  • Logic Framework – assumption, evidence, conclusion

  • Weakening – counter evidence, alternative explanation, irrelevancy, fake weakening, two weakening options

  • Strengthening – supporting evidence, supplementary evidence, reference case, assumption, weakening approach, two strengthening options

  • Assumption – missing evidence, assumption confirmation/negation test

  • Conclusion – “A+B=C”, contradiction, paraphase, quantitative (ratio, proportion, rate, mean etc)

  • Inference – differences with conclusion, over-inference

  • Evaluation – quantitative, qualitative (=assumption)

  • Logical Flaws – sample bias, different baseline, hasty generalization, suppressed evidence, false cause

  • General Requirements – direct and straightforward, no absolute words in conclusions/inference, reference case not valid for weakening, linkage between evidence and conclusion, hit key points in evidence

Verbal - RC

  • Reading – skimming techniques

  • Theme – science, politics, business, social, history, arts

  • Tone – neutral, evaluative, critical

  • Logical Structure – inflexion, causality, conditional, parallel, progression 

  • Ideation – stated or inferred ideas, unmentioned ideas, primary purpose of passage

  • Key Words – words repeatedly used, difficult words, "However"

  • CR Type – weakening, strengthening, assumption, conclusion, inference, evaluation
