Help Students Catch Up With Free Online STEM Courses

Free Online STEM Courses

Can you believe it’s been two years since the pandemic changed the way we teach? By now, it’s clear things aren’t going back to some kind of pre-pandemic normal – even for students who have returned to in-person classes, the lingering effects of remote learning and missed classes will be felt for a long time to come.

As educators have seen firsthand, many students struggled with remote learning and urgently need interventions to help them catch up. But as educators, it’s difficult to balance these students’ needs with the demands of a curriculum and the needs of their peers. In many cases, it’s simply too much to ask of our teachers, no matter how hard you work. That’s why we think our free online courses could be so helpful – for both educators and their students.

On our online learning platform, we offer 18 free online courses in core STEM subjects, from algebra, statistics and calculus to biology, chemistry and physics. If you think your students might benefit from high quality, in-depth video lessons outside of class time, our online courses could be the perfect resource.

We know how hard teachers and professors work every day to give students the best education possible. We can help. Share our free online courses with your students so they can brush up, catch up or get ahead in the areas where they need it most. Browse all 18 of our free online STEM courses and check out some of the available subjects below!

Calculus & Precalculus

With three full calculus courses on offer, we have the resources your students need to wrap their heads around differentials, derivatives and integrals – it’s all here. Check out our Calculus 1/AB Course, our Calculus 2/BC Course, and our Calculus 3 Course. In addition, we offer an in-depth Precalculus Course made up of over 330 different lectures.


From basic Newtonian physics to relativity, our physics courses cover the breadth of physics concepts across nearly 700 different lectures. Take a look at our Physics 101: Mechanics Course, our Physics 102: Electricity and Magnetism Course, and our Physics 103 Course to see the resources on offer for your students.


With three courses to choose from, beginning and advanced students alike will benefit from our chemistry courses. In our Chemistry 101 Course, students will be introduced to chemistry topics like the periodic table and its properties, molecular bonding, states of matter, and chemical reactions. Our Chemistry 102 Course covers thermodynamics, kinetics, nuclear chemistry and much more. And finally, our Organic Chemistry Course provides students with 26 free lectures on core concepts in organic chemistry.


In our Algebra Course, students will be introduced to the fundamentals of algebra and go deep on linear functions, equations and graphs across 6 topics and 235 lectures. In our Algebra 2 Course, students will study 11 topics and 366 lectures on subjects such as polynomials, matrices and determinants, quadratic equations and functions, and trigonometric functions to take their algebra skills to the next level.


Our Intro to Statistics & AP Statistics Course is covers 9 topics across 160 lectures, including data and stats, probability, numerical summaries, linear regression and correlation, normal, binomial, and geometric models, sampling distributions, confidence intervals, hypothesis testing and more.


In our Biology Course, your students can learn about topics such as the basic chemistry of life, metabolism, the cell, cellular respiration and fermentation, photosynthesis, cell signaling, gene expression, the cell cycle and cellular reproduction, mendelian genetics, viruses, and genomics and biotechnology.


With extensive video lessons on parallel and perpendicular lines, right angles, circles, rigid and non-rigid transformations, relationships within triangles, properties of quadrilaterals, volume, and more, students can master 12 topics and access 101 lectures in our Geometry Course.

Computer Science

Our AP CS Course begins with a basic computer science concepts and introduction to Java, then moves into important programming concepts such as arithmetic and logical expressions, conditional statements, loops, one-dimensional and 2D arrays, recursion, strings, and more. The course also covers the basic searching and sorting algorithms, as well as Object Oriented Programming concepts in Java with an introduction to classes, interfaces in Java, and the implementation of inheritance and polymorphism. In addition, the course helps students understand the design environment and how to find errors.

SAT & ACT Practice

In addition to our STEM courses, we also offer a free SAT Course and ACT Course for students to prepare for their standardized tests. Our SAT Course mainly covers topics in math and English, with lessons from SAT prep experts designed to help students improve their scores. Math lessons cover SAT algebra, geometry, trigonometry, probability, statistics, and more. English SAT lessons focus on reading and essay writing. Our ACT Course covers the English, math, reading, science sections of the exam.
