Illinois Olympiad Preparation — Grade 12
Comprehensive Course Syllabus
Course Overview
Our Illinois Grade 12 Olympiad programme is the most advanced level of this enrichment course in competitive mathematics and science, designed to run alongside — never instead of — a student’s regular high school coursework.
The proof and number theory core is demanding: proof by contradiction and contrapositive, strong induction, congruences and modular equations, Fermat’s little theorem, Euler’s totient function, the Chinese Remainder Theorem, Diophantine equations, and divisor functions.
The algebra strand covers olympiad algebraic manipulation, polynomial problems with symmetric polynomials and Vieta’s relations, inequalities including AM-GM Cauchy-Schwarz and rearrangement, advanced inequality strategies with normalization and convexity, recurrence relations, and functional equations with injectivity and surjectivity.
The discrete strand is substantial: combinatorics, inclusion-exclusion, generating functions, bijections, the pigeonhole principle in both forms, invariants and monovariants, graph theory with Euler paths spanning trees and bipartite graphs, and probability with linearity of expectation.
The geometry strand covers Euclidean geometry with all four triangle centres, circle geometry with power of a point, coordinate geometry, olympiad trigonometry, and advanced strategies including auxiliary lines angle chasing area methods and an introduction to inversion.
The course closes with mathematical games, the extremal principle, constructions, advanced logic, olympiad physics chemistry and biology, computational thinking with dynamic programming, contest strategy with mock competitions, and a capstone portfolio.
Olympiad Problem-Solving Foundations
Problem Interpretation
Students interpret problems carefully. Misreading is the commonest failure.
Identifying Constraints
Students identify constraints. Constraints often carry the key insight.
Pattern Recognition
Students recognise patterns. Patterns shortcut long calculation.
Decomposition
Students decompose problems. Decomposition makes problems tractable.
Strategic Thinking
Students think strategically. Strategy chooses the approach.
Advanced Mathematical Reasoning
Logical Statements
Students analyse logical statements. Statements are true or false.
Implication
Students analyse implication. Implication is the core logical relation.
Converse
Students form converses. A converse is not logically equivalent.
Contrapositive
Students form contrapositives. The contrapositive is always equivalent.
Necessary Conditions
Students identify necessary conditions. A necessary condition must hold.
Mathematical Proof Techniques
Direct Proof
Students write direct proofs. Direct proof works forward from the given.
Proof by Contradiction
Students prove by contradiction. Assume the opposite and derive absurdity.
Proof by Contrapositive
Students prove by contrapositive. The contrapositive is sometimes far easier.
Mathematical Induction
Students prove by induction. Induction proves statements for all integers.
Strong Induction
Students use strong induction. Strong induction assumes all earlier cases.
Number Theory Foundations
Divisibility
Students study divisibility. Divisibility is the core relation.
Prime Numbers
Students study primes. Primes are the multiplicative building blocks.
Composite Numbers
Students study composites. Composites factor into primes.
Factors
Students find factors. The factor count follows from prime factorisation.
Multiples
Students find multiples. Multiples are products with integers.
Advanced Number Theory
Congruences
Students use congruences. Congruence compares remainders.
Modular Equations
Students solve modular equations. Modular equations have periodic solutions.
Fermat's Little Theorem
Students use Fermat’s little theorem. The theorem simplifies large powers modulo a prime.
Euler's Totient Concept
Students study Euler’s totient. The totient counts coprime integers.
Chinese Remainder Theorem Introduction
Students meet the Chinese Remainder Theorem. It solves simultaneous congruences.
Prime Numbers & Arithmetic Functions
Prime Distribution
Students study prime distribution. Primes thin out but never stop.
Prime Factorization
Students use prime factorisation. Factorisation underpins arithmetic functions.
Divisor Functions
Students study divisor functions. Divisor functions summarise factorisation.
Number of Divisors
Students count divisors. The count follows from the exponents.
Sum of Divisors
Students sum divisors. The sum has a product formula.
Olympiad Algebra
Algebraic Manipulation
Students manipulate algebraically. Manipulation direction matters.
Polynomial Expressions
Students handle polynomial expressions. Polynomials appear throughout olympiads.
Factoring
Students factor expressions. Factoring reveals structure.
Equations
Students solve equations. Equations state exact relationships.
Systems
Students solve systems. Systems combine constraints.
Polynomial Problems
Polynomial Equations
Students solve polynomial equations. Higher degrees need theorems.
Roots
Students find roots. Roots are where the polynomial vanishes.
Factorization
Students factor polynomials. Factorisation exposes the roots.
Symmetric Polynomials
Students study symmetric polynomials. Symmetry simplifies many expressions.
Vieta's Relations
Students apply Vieta’s relations. Vieta relates coefficients to roots.
Inequalities
Basic Inequalities
Students apply basic inequalities. Basic inequalities are the toolkit.
AM-GM
Students apply AM-GM. The arithmetic mean is at least the geometric mean.
Cauchy-Schwarz
Students apply Cauchy-Schwarz. It bounds sums of products.
Triangle Inequality
Students apply the triangle inequality. The inequality generalises beyond triangles.
Rearrangement Concepts
Students meet rearrangement. Similarly ordered sequences maximise the sum of products.
Advanced Inequality Strategies
Variable Substitution
Students substitute variables. Substitution can reduce the number of variables.
Normalization
Students normalise. Normalisation fixes a sum or product to simplify.
Bounding
Students bound expressions. Bounding chains several inequalities.
Symmetry
Students exploit symmetry. Symmetric problems often have symmetric extrema.
Convexity Introduction
Students meet convexity. Convexity gives Jensen’s inequality.
Sequences & Series
Arithmetic Sequences
Students study arithmetic sequences. These add a constant difference.
Geometric Sequences
Students study geometric sequences. These multiply by a constant ratio.
Recurrence Relations
Students solve recurrence relations. Recurrences define sequences implicitly.
Recursive Sequences
Students study recursive sequences. Each term depends on earlier ones.
Partial Sums
Students compute partial sums. Partial sums reveal the pattern.
Functional Equations
Function Definitions
Students define functions precisely. Precision matters in functional equations.
Substitution
Students substitute values. Clever substitution is the main technique.
Symmetry
Students exploit symmetry. Symmetric substitutions reveal structure.
Injectivity
Students prove injectivity. Injectivity means distinct inputs give distinct outputs.
Surjectivity
Students prove surjectivity. Surjectivity means every output is achieved.

Standards Note
This Olympiad programme is an enrichment course. It is designed to run alongside a student’s regular school mathematics and science courses, never instead of them. It does not replace Illinois high school graduation requirements and is not a substitute for any required coursework.
This programme is not affiliated with, endorsed by, or connected to any competition, examination body, university, or organisation. It is not affiliated with the American Mathematics Competitions, the Mathematical Association of America, the American Invitational Mathematics Examination, the USA Mathematical Olympiad, Science Olympiad, the International Olympiads, the College Board, Advanced Placement, or any college entrance examination.
Enrolling in this course does not guarantee qualification for any competition, any particular score, any ranking, any medal, any award, any scholarship, or any admission outcome. Competition results depend on many factors outside any course’s control, and olympiad performance is not required for admission to any university.
Competitions and olympiads each set their own eligibility rules, syllabi, formats, and registration procedures, and these change from year to year. Families are responsible for checking the current requirements of any competition they intend to enter directly with its organisers. This course does not register students for any competition.
The content here goes well beyond the Illinois Learning Standards and beyond most undergraduate first-year material in places. Topics such as Fermat’s little theorem, generating functions, inversion, convexity, and dynamic programming are typically encountered at university. This is intentional enrichment.
Olympiad preparation at this level is demanding and is not suitable for every student. Grade 12 is already an intense year in Illinois, with college applications, coursework, and often employment. Students should not take on this workload at the expense of their school performance, applications, sleep, health, or other interests. It is entirely reasonable to step back from competition preparation in the senior year.
Evolution and natural selection are taught as established science, and students examine fossil, anatomical, molecular, and population-genetic evidence directly.
All chemistry content is theoretical and calculation-based. No hazardous practical work is set. Students are never asked to handle hazardous chemicals or apparatus requiring laboratory conditions.
Success in olympiad problems is built through sustained practice over years, not weeks. Progress is often uneven, and spending hours on a single problem without solving it is the normal experience of everyone who does this work, including professional mathematicians.
It is important to distinguish between competition syllabi published by competition organisers and the course structure created for this educational programme, which organises Grade 12 olympiad preparation into a month-by-month teaching sequence.
