The International Baccalaureate (IB) study platform RevisionDojo has launched a "Back to School" update with new AI-powered study and coursework tools. While the platform's self-reported survey results show gains in predicted grades, academic experts warn families to treat these indicators with caution. As students return to classes, balancing app-based preparation with school grading and academic integrity guidelines is important.
What Happened
In its latest launch, RevisionDojo released its 2026 Back to School Update. The update includes features like the "Coursework Studio," AI-supported feedback through "Research Jojo," and speaking practice tools for oral assessments. The company also published findings from its self-reported May 2026 State of Learning Survey. This survey tracked 1,168 matched subject ratings from students across 258 schools and reported that average predicted grades increased from 4.81 to 5.58 on the IB's 7-point scale.
The survey reported an average predicted score boost of 31.10 to 34.95 out of 45 for full diploma students. RevisionDojo also stated that ten out of twelve teachers surveyed had lower stress levels, with average stress ratings dropping by more than 40% after using the platform. The company noted that these self-reported results do not prove direct causation.
The Bigger Picture
While these results seem positive, educators note a persistent gap between predicted grades and actual exam results. Predicted grades are historically optimistic. Research shows that only 50% to 60% of predicted IB grades match final results, and 30% to 35% of student scores are overpredicted. Teachers calculate these predictions using mocks, classwork, and internal assessments. If teachers overestimate performance, or if coursework marks drop during external moderation, final results will fall short.
Families should also avoid mistaking platform activity for actual understanding. As we previously reported, cognitive psychologists warn that high engagement with gamified study apps does not always lead to deep learning.
The rise of AI tools in apps like RevisionDojo also creates academic risks. The IB organization does not ban artificial intelligence, but it enforces strict rules for transparent use. Students can use AI to outline coursework, brainstorm questions, or check grammar, but they cannot use AI to draft actual essay paragraphs or generate scientific data. Uncredited AI use can result in zero marks and a loss of the diploma.
AI tools also show mixed results in classrooms. While RevisionDojo's small pilot showed stress reduction, broader national studies present a different picture. A recent YouGov survey of UK teachers found that while AI adoption has doubled, it had a limited impact on reducing working hours. At the same time, 57% of secondary teachers reported suspecting students of submitting unauthorized, AI-generated assignments, creating new academic honesty issues.
What This Means for Families
For parents and students in the demanding IB program, revision tools can provide structure, but they do not replace school-aligned work. School teachers, not apps, calculate the predicted grades submitted to universities during college applications.
Families must ensure that students use automated feedback tools ethically. Over-reliance on AI helpers to write portions of Extended Essays (EE) or Theory of Knowledge (TOK) papers can trigger school plagiarism flags or external IB penalties.
What You Can Do
- Check your school's specific academic integrity policy. If your child uses tools like "Research Jojo" or AI essay helpers, ensure they only use them for outlining and brainstorming, never for writing text.
- Do not rely solely on study app metrics or local leaderboard rankings. Review actual timed, paper-based mock exam results provided by teachers to get an accurate view of performance.
- Keep a clear log of essay drafts, brainstorm notes, and research sources. This history provides proof of original work if a school's AI-detection software flags a student's coursework.
