I wrote this summative assessment for my IB/Precalculus students to test primarily their understanding of derivatives. However, it is mostly based on spiral review concepts, as I anticipate the IB exam will be: it includes applications of the first derivative, writing equations of parabolas in vertex form, finding the equation of a line tangent to a function at a specific point, solving equations using logs, Venn diagrams, writing expressions in closed form, double-angle formulas, and using z-
