Illinois Olympiad Preparation — Grade 11

Comprehensive Course Syllabus

Course Overview

Our Illinois Grade 11 Olympiad programme is an advanced enrichment course in competitive mathematics and science, designed to run alongside — never instead of — a student’s regular high school coursework.

The mathematics core is demanding: proof techniques, number theory through Diophantine equations congruences and an introduction to the Chinese Remainder Theorem and Euler’s totient function, algebraic manipulation, equations with parameters, functional equations, recurrence relations, and inequalities including AM-GM and Cauchy-Schwarz.

The geometry strand covers Euclidean geometry, all four triangle centres, circle geometry with power of a point, coordinate geometry, transformations and symmetry, olympiad trigonometry, and a full module on advanced geometric problem solving with auxiliary lines, angle chasing, and area and ratio methods.

The discrete strand covers combinatorics, the pigeonhole principle, inclusion-exclusion, generating functions, probability with Bayes’ theorem and expected value, statistics, discrete mathematics with graphs and networks, mathematical games with winning strategies, invariants and monovariants, and strong induction.

The science strand covers olympiad physics including projectile and circular motion gravitation and circuits, chemistry including equilibrium redox thermochemistry gas laws electrochemistry and organic chemistry, biology including genetic crosses population genetics and physiology, and Earth and environmental science.

The course closes with scientific data analysis, experimental design, estimation and mental mathematics, competition strategy and time management, mock olympiads with error classification, and a capstone with independent problem solving and solution writing.

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 Algebra II, Precalculus, Chemistry, Physics, or Biology coursework.

This programme is not affiliated with, endorsed by, or connected to any competition, examination body, or organisation. It is not affiliated with the American Mathematics Competitions, the Mathematical Association of America, the American Invitational Mathematics Examination, 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, including a student’s own preparation, the difficulty of a given year’s paper, and the field of other participants.

Competitions, olympiads, and enrichment programmes 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 for this grade by design. Topics such as the Chinese Remainder Theorem, Euler’s totient function, generating functions, Cauchy-Schwarz, strong induction, electrochemistry, and population genetics are typically encountered in later coursework or at university. This is intentional enrichment, not an accelerated replacement for the standard sequence.

Olympiad preparation at this level is demanding and is not suitable for every student. Grade 11 is already an intense academic year in Illinois, with statewide assessment and college preparation. Students should not take on this workload at the expense of their school performance, sleep, health, or other interests.

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. Any demonstration or home activity uses safe household materials with adult supervision. Students are never asked to handle hazardous chemicals, strong acids or bases, or apparatus requiring laboratory conditions.

Success in olympiad problems is built through sustained practice over years, not weeks. Progress is often uneven, and struggling with a hard problem for a long time is the normal experience rather than a sign of failure.

It is important to distinguish between competition syllabi published by competition organisers and the course structure created for this educational programme, which organises Grade 11 olympiad preparation into a month-by-month teaching sequence.
