@SkiaSharp @SkiaSharp Bit the bullet and converted code base to v3, that change was easy to fix. Took the opportunity to handle the deprication of fonts in SKPaint, which took more time but makes sense, too. To me, feels like good time to do it, and worth it for the benefits of v3

Here's the new spider diagram in action with a more complicated question. The spider model is available for example questions and as model answers after the question has been marked.

Here's something we've been working on for schools with 23 Equations accounts. Example and Model answers can now be shown as "Spider Models", an different way of picturing calculations. This is possible because the questions are built intelligently using the underlying model.

Good luck to everyone with the new term! And a reminder, 23Equations can still help your GCSE students with things not on the equation sheet. E.g., learning units and converting between prefixes. #Physicsrevision #gcsescience #gcsephysics

@RCampbellTeach @prof_di_chimica Great to read how people are using the app. The bus journey to and from school was exactly the kind of spare time the app was aimed to fill.

Tests are automatically marked (and it understands units and numbers, so either 200 ms or 0.2 s is fine) If you choose, help is available at the beginning of the test. For example, see an example answer to a similar question.

You may have noticed the new version of 23 Equations is being rolled out. The big new feature is School Room The app is aimed at helping students revise Physics anywhere, anytime. Now, teachers can set tests to provide guidance and structure to their revision.

New version of 23Equation now includes equation lists and questions based on IGCSE specs. Questions are based on models so are always different, can offer support such as showing example or suggesting the next step. Even generating another similar question! #IGCSE #IGCSEPhysics

Shiny new update to 23Equations. Lots of work to make it smoother and even nicer to use, resize things and swipe around. Back to working great on old version of iPad/iPhone back to IOS 9.3 so even IPhone 4s! The calculator, casio-like but only what's needed, now also standalone

IGCSEs also planned for next version. Snells law for example, is working really. The delay is due to the complexity of integrating the various specs.
