# IB Maths Help > IB Maths Help (ibmathshelp.online) is an auto-graded practice platform for IB Mathematics, covering all four courses -- Analysis & Approaches (SL and HL) and Applications & Interpretation (SL and HL) -- with over 10,200 exam-style practice questions, full worked solutions, GDC (graphing calculator) steps, and instant auto-marking of typed answers (integers, fractions, surds, pi multiples, logarithms, algebraic expressions). Every topic and sub-topic in the IB Mathematics syllabus is covered, with questions labelled by Paper 1/Paper 2, difficulty, and calculator/non-calculator status. Diagrams are drawn to each question's own real numbers, not generic placeholders. A teacher test-builder generates printable tests with a full answer key. ## Core pages - [Home](https://ibmathshelp.online/): overview, auto-grading demo, FAQ. - [Practice: Analysis & Approaches SL](https://ibmathshelp.online/practice/aa-sl/): full AA SL topic list and question bank. - [Practice: Analysis & Approaches HL](https://ibmathshelp.online/practice/aa-hl/): full AA HL topic list and question bank. - [Practice: Applications & Interpretation SL](https://ibmathshelp.online/practice/ai-sl/): full AI SL topic list and question bank. - [Practice: Applications & Interpretation HL](https://ibmathshelp.online/practice/ai-hl/): full AI HL topic list and question bank. - [Browse all topics](https://ibmathshelp.online/browse-topics): every topic across all four courses in one list. - [Full sitemap](https://ibmathshelp.online/sitemap): every practice topic page linked directly, one page. - [Formula booklet reference](https://ibmathshelp.online/formulas): the IB formula booklet content, organised by topic. - [Annotated formula booklet](https://ibmathshelp.online/booklet): every formula with a plain-English note, printable. - Formula booklet explained, per course: [AA SL](https://ibmathshelp.online/formulas/aa-sl), [AA HL](https://ibmathshelp.online/formulas/aa-hl), [AI SL](https://ibmathshelp.online/formulas/ai-sl), [AI HL](https://ibmathshelp.online/formulas/ai-hl). - [GDC guide](https://ibmathshelp.online/gdc): 57 guides for the calculations that come up most, each with steps for the TI-84 Plus CE, Casio fx-CG50/CG100 and TI-Nspire CX together. ## Internal Assessment (IA) guidance - [IA guide](https://ibmathshelp.online/ia-guide): how to plan and write the Mathematical IA. - [IA topic ideas](https://ibmathshelp.online/ia-topics): 100+ Exploration topic ideas, filtered by theme, level and course. - [IA planner](https://ibmathshelp.online/ia-planner): 7-stage workflow and a personal timeline generator. - [IA marking criteria](https://ibmathshelp.online/ia-criteria): all 5 criteria (A-E) explained with worked examples. - [IA checklist](https://ibmathshelp.online/ia-checklist): interactive pre-submission checklist. - [IA common pitfalls](https://ibmathshelp.online/ia-pitfalls): the mistakes IB examiners see most often, and how to avoid them. - [Google Sheets guide](https://ibmathshelp.online/ia-skills): summary statistics, regression, Pearson's r, chi-squared, for the IA. - [Data sources](https://ibmathshelp.online/ia-data): curated free datasets for the IA, by topic. - [Equation editor guide](https://ibmathshelp.online/ia-equation): writing maths properly in Google Docs / LaTeX for the IA. - [GeoGebra guide](https://ibmathshelp.online/ia-geogebra): graphs, regression, sliders and 3D diagrams for the IA. ## Pricing - [Pricing](https://ibmathshelp.online/#pricing): free to start, with sample topics in every course (practice and exam modes, full worked solutions, auto-graded answers, the formula companion and the GDC guide). - Full access is a single one-off payment of £75 for every question across all four courses.
