Path to a free self-taught education in Math!

Contents

Summary

The OSSU curriculum is a complete education in mathematics using online materials. It's for those who want a proper grounding in concepts fundamental to all math disciplines, and for those who have the discipline, will, and good habits to obtain this education largely on their own, but with support from a worldwide community of fellow learners.

It is designed according to the degree requirements of undergraduate math majors, minus general education (non-math) requirements, as it is assumed most of the people following this curriculum are already educated outside the field of math. The courses themselves are among the very best in the world, often coming from Harvard, MIT, Stanford, etc., but specifically chosen to meet the following criteria.

Courses must:

  • Match our curricular guidelines the 2015 CUPM Guide.
  • Be open for enrollment
  • Run regularly (ideally in self-paced format, otherwise running multiple times per year)
  • Be of high quality in teaching materials and pedagogical practice

When no course meets the above criteria, the coursework is supplemented with a book.

Duration. It is possible to finish the curriculum within about 2 years if you plan carefully and devote roughly 18-22 hours/week to your studies.

Cost. OSSU strives to identify free resources to reach your learning goal. However, some courses may charge money for assignments/tests/projects to be graded.

Decide how much or how little to spend based on your own time and budget; just remember that you can't purchase success!

Process. Students can work through the curriculum alone or in groups, in order or out of order.

  • For simplicity, we recommend working through courses in order from top to bottom, as they have already been sorted by their prerequisites.
  • Courses in Core Mathematics are the basic requirements for all OSSU Math students, and provide a foundation for deeper study. Take all of these courses.
  • Courses in Advanced Topics are electives. Take one course in each topic area. Then choose one topic you want to become an expert in and take all the courses under that heading. You can also create your own custom subject (we recommend getting validation from the community on the subject you choose).

Content policy. If you plan on showing off some of your coursework publicly, you must share only files that you are allowed to. Respect the code of conduct that you sign in the beginning of each course!

Code of conduct

OSSU's code of conduct.

Curriculum

The curriculum is separated into two parts:

Core Mathematics

All OSSU Math students need to take all of these courses. Subjects include:

  • Introduction to Mathematical Thinking
  • Single-Variable Calculus
  • Multi-Variable Calculus
  • Introduction to Differential Equations
  • Discrete Math
  • Linear Algebra
  • Probability & Statistics
  • Intro to Analysis
  • Intro to Abstract Algebra

Introduction to Mathematical Thinking

Most people's views of mathematics are destroyed in school by focusing on memorization and regurgitation. But mathematicians see math as an elegant way to explain the world around us. This class covers how to think like a mathematician and solve problems.

Topics covered: Mathematical mindset Number Theory

Courses Duration Effort Prerequisites
Introduction to Mathematical Thinking 10 weeks 4 hours/week none

Calculus

Calculus is the study of infinity. As the cornerstone of geometry and physics, it serves as the foundation of our world, explaining the phenomena that underly our technology, our planets, and our hearts.

Topics Covered: Derivatives Integrals Infinity

Courses Duration Effort Prerequisites
Calculus 1A: Differentiation alt 13 weeks 6-10 hours/week high school math
Calculus 1B: Integration alt 13 weeks 5-10 hours/week Calculus 1A
Calculus 1C: Coordinate Systems & Infinite Series alt 6 weeks 5-10 hours/week Calculus 1B
Multivariable Calculus 12 weeks 6 hours/week Calculus 1C

Introduction to Differential Equations

Differential equations describe the science of change: the route by which natural and man-made systems move from one state to another. Epidemics, population growth, and weather patterns are all modeled using differential equations.

Topics covered: First-order ODEs Second-order ODEs Higher-order ODEs Laplace Transforms

Courses Duration Effort Prerequisites
Introduction to Differential Equations 14 weeks 3-6 hours/week Calculus 1C

Discrete Mathematics

Discrete mathematics is the mathematics of objects and ideas. The topics discussed here also form the basis of the field of computer science. For mathematics majors, a discrete math course is usually also a first introduction to formal proofs.

Topics covered: Counting Grouping Classifying Logic and Reasoning

Courses Duration Effort Prerequisites
Mathematics for Computer Science 14 weeks 6-8 hours/week Calculus 1C

Linear Algebra

Linear algebra is the mathematics of spatial relationships. It provides an elegant way to consider many simultaneous equations, to visualize arbitrarily-many dimensions, and to explain complex phenomena in simple terms.

Topics covered: Vector and matrix calculations Linear transformations Vector spaces Eigenvalues and Eigenvectors

Courses Duration Effort Prerequisites
Essence of Linear Algebra - - high school math
Linear Algebra 14 weeks 12 hours/week Essence of Linear Algebra

Probability & Statistics

Probability is the mathematics of uncertainty. Statistics is the mathematical framework for quantifying uncertainty in real-world data. These two related but distinct fields of study help us describe variation and uncertainty in the world around us. These courses make heavy use of discrete mathematics, linear algebra, and calculus, and serve as a first opportunity to apply what you've learned in the other core courses.

Topics covered: Random variables Expectation and Variance Probability Distributions

Courses Duration Effort Prerequisites
Probability 14 weeks 12-16 hours/week Multivariable Calculus, Linear Algebra, Math for Computer Science
Statistics for Applications 14 weeks 12-16 hours/week Probability

Introduction to Analysis

Analysis is the mathematics of mathematics itself. Analysis makes extensive use of the formal proof to build important mathematical concepts from the ground up. Starting by proving the existence of real numbers, this course will show you how to create single-variable calculus entirely from scratch.

Topics covered: Proofs Real analysis

Courses Duration Effort Prerequisites
Introduction to Analysis 14 weeks 8-10 hours/week Multivariable Calculus
Supplemental Lecture Videos 16 weeks 8-10 hours/week Multivariable Calculus

Introduction to Abstract Algebra

Abstract algebra (occasionally called modern algebra) is the study of algebraic structures. Algebraic structures include groups, rings, fields, modules, vector spaces, lattices, and algebras. The term abstract algebra was coined in the early 20th century to distinguish this area of study from older parts of algebra, and more specifically from elementary algebra, the use of variables to represent numbers in computation and reasoning.

Topics covered: Group Theory Rings and fields

Courses Duration Effort Prerequisites
Introduction to Abstract Group theory 8 weeks 8-10 hours/week High school mathematics
Introduction to Rings and Fields 8 weeks 8-10 hours/week Introduction to Abstract Group Theory

Once you've completed all courses in Core Mathematics, you are free to take elective courses in Advanced Topics, which include:

  • Differential Equations
  • Mathematical Logic
  • Geometry
