IB Physics theory lessons
Short video lessons explain difficult topics in the context of the IB Physics course. Students can study at their own pace and return to a lesson whenever a concept needs another look.
Sirius Study is an IB Physics learning platform that helps Standard Level and Higher Level students understand the course, prepare for exams, and see how marks are earned.
We built the IB Physics platform that we wished existed: one that features the theory needed and that helps students to put the learning into practice with their exams.
Learn the Physics, check your understanding, then prepare for the paper.
Short video lessons explain difficult topics in the context of the IB Physics course. Students can study at their own pace and return to a lesson whenever a concept needs another look.
Learning checks help students confirm what they understood, while course progress keeps the recommended next step clear. A lesson counts as complete after the video and learning check are completed.
Plus includes exam-answer walkthroughs, paper strategy, mark scheme commentary, and common-mistake analysis. The aim is to show not only the Physics, but what to write and why it earns marks.
Built around the decisions an IB Physics student faces while learning and revising.
The course is for IB Physics rather than general Physics study. Lessons connect concepts to the syllabus, command terms, paper format, and the way answers are marked.
Understanding a concept and writing a mark-earning answer are related but different skills. Sirius Study teaches both instead of assuming that one automatically produces the other.
Students can create an account and use the theory course without payment. Plus is a separate, one-time purchase for six months of exam-preparation content.
Progress does not move simply because a page was opened. It reflects completed lesson activity so students can see what they have covered and what comes next.
The platform is designed for a student revising independently, including clear next steps, exam countdowns, and lessons that can be revisited whenever they are needed.
A platform designed by a teacher who cares about you.
Mitch Campbell is the teacher and founder behind Sirius Study. He leads its lessons and teaching approach, connecting Physics explanations with the answer structure students need in IB exams.
Sirius Study began with a recurring frustration: students can understand the theory and still lose marks because they do not know how to express that understanding on the paper. The platform was built to close that gap.
