What the SL AA bridging course covers
Analysis and Approaches SL expects you to do algebra by hand from the first weeks of DP1, and Paper 1 is sat without a calculator. The six-week course builds that fluency in order:
- Week 1, number and algebra: number systems, scientific notation, algebraic manipulation and absolute value.
- Week 2, solving equations: linear equations, quadratics, simultaneous equations and algebraic fractions.
- Week 3, exponents, surds and sets: the laws of exponents, simplifying and rationalising surds, and set notation.
- Week 4, functions and coordinate geometry: mappings and relations, linear and quadratic graphs, gradients, midpoints and distances.
- Week 5, geometry and trigonometry: Pythagoras' theorem, right-angled trigonometry, and 2D and 3D shapes.
- Week 6, stepping into the DP: sequences and logarithms, with applications.
Every sub-topic has worked examples and then practice questions with full solutions, and each week ends with a four-question check that feeds your readiness score. Week 1 also has two optional questions where you upload a photo of your written working for AI marking.
The 15-question diagnostic covers the same ground at three levels. It asks you, for example, to find 82/3 without a calculator, to find the inverse of f(x) = 2x − 5 and to show that x² − 4x + 5 = 0 has no real roots. Take it first to see which weeks you can move through quickly.
