IB study platforms at a glance
Most IB study platforms are very good at one particular thing. Some are built around question practice, some are mainly libraries of notes or videos, and others are designed for coursework examples or classroom use. The right choice is less about finding one universal winner and more about knowing what kind of support you actually need.
RevisionDojo is designed as an all-in-one IB workspace. Its syllabus-aligned notes, IB questionbank, and test builder let you learn a topic, practise it, and then sit a timed paper in one workflow. Students preparing for the next exam session can also use current-syllabus predicted papers. For assessed work, the IB coursework grader gives criterion-level feedback on Internal Assessments, the Extended Essay, and Theory of Knowledge drafts. Students can compare that feedback with graded coursework exemplars, follow the IA, EE, and TOK guides, or practise a language assessment with the Individual Oral grader.
For everyday revision, explore the interactive lessons, active-recall flashcards, worked videos, and past-paper walkthroughs. Jojo can then help explain mistakes inside the AI study chat. Teachers can review the separate RevisionDojo for Schools tools for assignments, class analytics, and marking workflows. Use this overview to make a shortlist rather than treating every green check as equal. Explore all RevisionDojo feature guides and check current pricing before deciding. For deeper evidence and trade-offs, open a platform name in the table or start with the Revision Village comparison or the Clastify comparison.
