About Syllabo: IB revision, made fun

Questions checked against the IB guides, marking that works the way an examiner marks, maths and science set like the exam paper, and full science lessons. Questions checked against the real exam • Maths, Physics, Chemistry, Biology, Economics, SEHS and Global Politics questions were reviewed against the IB guides, and the errors found were fixed. • Many Maths AA and Biology questions were rewritten to read and mark like real paper questions. • True or false items are now real multiple choice, near-identical questions became different ones, and extra calculation drills beyond what the papers set were taken out. • Global Politics questions are now real paper parts, including essays and Paper 3 questions on your own researched case. • Chemistry, Biology, Physics, Maths and Economics follow their current IB guides. Questions on topics the guides dropped are gone. Marking like an examiner • Essays are marked by level bands, as the IB marks them. Without AI marking, Syllabo no longer guesses: it shows the bands and a model answer and asks how it went. • Error carried forward: a later step done right with your own wrong earlier value still earns its mark. • Number answers follow IB rounding: exact or 3 significant figures in maths. • Copying the question back, giving two answers to cover both, or listing keywords no longer earns marks. • A calculation followed by a choice, such as "PED = 2, so demand is elastic", earns both marks. • An answer that says the opposite of the mark scheme ("does not release oxygen") no longer earns the mark, and "1,000 kg" is read as one thousand. Typeset like the paper • Maths AA and AI questions, answers and the formula booklet show fractions stacked, powers on the right bracket, limits on integrals and matrices in brackets. • Physics, Chemistry, Biology and the other science subjects show formulas, units and nuclides as the paper prints them, in questions, booklets and lessons. • The tutor's maths is typeset the same way. New questions, not repeats • Sessions give you questions you haven't done before. A question you got wrong doesn't come back as it was: you get a similar one with other numbers or wording, so you learn the method rather than the answer. Getting that one right fixes the mistake. To redo the original, open it from Mistakes. Lessons for Chemistry, Physics and Biology • Every topic has a full written lesson with worked examples and quick checks, and it works offline. Quick sessions that fill their time • Five and ten minute sessions now hold five and ten minutes of questions, with one question that needs working. A calculator outside maths • Number answers in other subjects get a calculator keypad with an = key. Physics adds sin, cos, tan, e and ln. Smaller fixes • Questions made from your notes no longer show the marker's instructions as the model answer. • Notes you import, and coins handed back to you, are kept when another device syncs. • Deleting an online account asks you to sign in again first, so it is deleted online too. • Rewards say "Ninja", not "Ninja skin".
