What the SL AI bridging course covers
Applications and Interpretation SL is about modelling real situations and using your graphic display calculator (GDC) well: both papers are sat with one. The six-week course mixes core number and algebra with the calculator skills the course leans on, shown on the Casio fx-CG50:
- Week 1: number systems, scientific notation and significant figures, approximation and error, expanding and factorising, and solving linear equations.
- Week 2: function notation, equations of straight lines, linear models of real situations, graphing and solving on the CG50, quadratics and the laws of indices.
- Week 3: Pythagoras' theorem, right-angled and non-right-angled trigonometry, 3D coordinates, and area, volume and surface area.
- Week 4: sets and Venn diagrams, tree diagrams, descriptive statistics and outliers, bivariate data and regression, and probability distributions on the CG50.
- Week 5: the sine and cosine rules, rearranging formulae, simultaneous equations, and a first look at calculus: the power rule, tangents, turning points and area by integration.
- Week 6: arithmetic and geometric sequences, sigma notation, compound interest and depreciation with the CG50's TVM solver, and exponential, linear and quadratic graphs.
Each sub-topic has worked examples followed by practice questions with solutions, and each week ends with a four-question check. The practice library also has a set on the CG50's Run-Matrix menu.
The 15-question diagnostic is built around context: a currency conversion, a 20% discount, a taxi fare as a linear model, depreciation of 15% a year, what a correlation coefficient of −0.85 tells you and what the edges of a Voronoi diagram mean.
