IAL Pure 3 Exponentials & Logarithms exam questions

Exam-style questions on exponentials and logarithms for Edexcel IAL Pure 3 (WMA13): e to the x, natural logarithms and modelling. With full solutions.

This resource covers the whole of Chapter 5 (Exponentials and Logarithms) of the Pearson Edexcel International A Level Pure Mathematics 3 course. All questions are original and written in the style of the WMA13 paper — these are not reproduced past paper questions.

What’s covered

The function e to the power x and its graph
Natural logarithms and the relationship between e and ln
Solving equations involving e and ln
Exponential growth and decay modelling
Using logarithms to reduce a relationship to linear form and find constants

How to use it

Works as homework, as consolidation across a sequence of lessons, or as revision before the WMA13 paper. The modelling questions are set in context and require interpreting the constants, not just solving for them, which is how WMA13 examines this chapter.
