Karnataka II PUC Logic (KSEAB) study plan

Karnataka II PUC Logic (KSEAB) · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Categorical Syllogism and Fallacies & Categorical Propositions and Immediate Inference

  • State the rules of validity for categorical syllogism (distribution of terms, rules of quality and quantity) and apply them to decide validity of at least ten standard-form syllogisms

  • Rewrite everyday arguments into standard form (major premise, minor premise, conclusion) and identify the mood and figure of each

  • Distinguish formal from informal fallacies and name the specific fallacy in ten given passages

  • Construct Venn diagrams for two-term and three-term categorical statements and use them to test validity

Your checkpoint

A handwritten or typed sheet of 20 syllogisms with mood, figure, validity verdict, and the rule violated for each invalid one, scored against an answer key

Week 2

Categorical Propositions and Immediate Inference & Terms, Propositions and Classification

  • Classify categorical propositions by quantity and quality and write their A, E, I, O forms with standard quantifier wording

  • State and apply the traditional square of opposition to derive contradictories, contraries, subcontraries, and subalterns

  • Perform conversion, obversion, and contraposition on given propositions and label each as valid or invalid

  • Identify and correct defects in definition (too broad, too narrow, circular, ambiguous) in given examples

Your checkpoint

A completed inference table showing all four relations and all three immediate-inference operations for ten given propositions, with validity marks

Week 3

Categorical Syllogism and Fallacies & Methods of Proof and Truth Tables

  • Translate natural-language arguments with 'only', 'unless', 'all but', and 'none but' into standard categorical form

  • Detect the fallacies of undistributed middle, illicit major, illicit minor, and four terms in prepared arguments

  • Reduce an enthymeme to its missing premise and test the completed argument

  • Write out the full truth-table test for validity on simple two-variable arguments

Your checkpoint

A one-page error log listing each syllogistic fallacy with your own original example and the rule it breaks, plus five enthymemes completed and tested

Week 4

Symbolic Logic: Propositional Calculus & Methods of Proof and Truth Tables

  • Symbolize compound statements using negation, conjunction, disjunction, conditional, and biconditional with consistent notation

  • Build complete truth tables for statements with up to three variables and classify them as tautology, contradiction, or contingent

  • Test argument validity by the indirect (short) truth-table method

  • Distinguish inclusive from exclusive disjunction and material from ordinary implication in given sentences

Your checkpoint

A timed set of 15 truth tables (at least five with three variables) fully worked with a tautology/contingency/contradiction verdict for each

Week 5

Symbolic Logic: Propositional Calculus & Methods of Proof and Truth Tables

  • Apply the rules of inference (modus ponens, modus tollens, hypothetical syllogism, disjunctive syllogism, constructive and destructive dilemma, simplification, conjunction, addition) in multi-step proofs

  • Apply the rules of replacement (De Morgan, commutation, association, distribution, double negation, transposition, exportation, material implication, equivalence) to transform formulas

  • Construct formal proofs of validity for at least eight symbolized arguments

  • Use conditional proof and indirect proof where direct derivation is awkward

Your checkpoint

Eight complete formal proofs written line by line with the justification cited for every step, checked against a key

Week 6

Inductive Reasoning and Scientific Method

  • Distinguish induction from deduction and identify kinds of induction: enumeration, analogy, causal inference, and statistical generalization

  • Explain Mill's methods (agreement, difference, joint method, concomitant variation, residues) and match them to described experiments

  • Outline the steps of the scientific method and the roles of hypothesis, prediction, experiment, and confirmation

  • Identify weaknesses in inductive arguments such as hasty generalization, false cause, and biased sample

Your checkpoint

A written analysis of three short scientific or everyday scenarios naming the inductive method used and evaluating the strength of the conclusion

Week 7

Nature and Scope of Logic & Logic and Language

  • Define logic, state its nature as a normative science of reasoning, and explain its relation to psychology and grammar

  • Distinguish sentence, proposition, and statement, and identify the cognitive and emotive uses of language

  • Explain the functions of language (informative, expressive, directive, performative) and detect emotive and persuasive uses in given passages

  • Identify and correct ambiguity, vagueness, and equivocation in given examples

Your checkpoint

A short essay of about 300 words distinguishing logic from psychology and grammar, with three original examples of language functions

Week 8

Categorical Syllogism and Fallacies & Symbolic Logic: Propositional Calculus & Inductive Reasoning and Scientific Method & Categorical Propositions and Immediate Inference

  • Review all eight domains using a checklist and re-solve one representative problem from each

  • Take two full-length timed mock papers under exam conditions and score them

  • Analyze every wrong answer, tracing it to a specific rule, definition, or symbolization error

  • Memorize the standard rule sets, square of opposition, and fallacy names for quick recall

Your checkpoint

Two scored mock papers with a corrected-answer review sheet listing each error, its cause, and the rule to recall

Milestones

Week 2: Can classify any categorical proposition, state all square-of-opposition relations, and perform conversion, obversion, and contraposition without notes

Week 4: Can symbolize a compound sentence and complete a three-variable truth table correctly in under ten minutes

Week 6: Can name and justify the inductive method in a described scenario and identify the fallacy in a weak inductive argument

Week 8: Scores at least 70 percent on both timed mock papers and can explain every error on the review sheet
