These Foundation modules are designed to develop your problem solving skills and provide an introduction to solving STEP (and STEP-like) problems. Most of the questions are taken from STEP I papers, with some STEP II questions appearing in later modules. The assignments also introduce mathematical ideas beyond the syllabus with lots of opportunities for extra reading.

Even if you are not intending to sit STEP I we strongly recommend that you work through these resources to develop your problem solving skills before attempting the STEP II (and later STEP III) modules. If your university offer only includes a STEP I paper then you should concentrate your efforts on the Foundation modules.

The modules are ordered so that the most recent one is at the top.

### STEP Support - Assignment 25

This module introduces integration by substitution. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 24

This module involves integration and an 18th century series problem. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 23

This module introduces the chain rule and asks some questions about coordinate geometry. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 22

This module derives some more differentiation results and asks you to sketch some graphs. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 21

This module introduces a couple of functions that might look familiar, and asks you to sketch some regions involving the modulus function. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 20

This module includes some differentiation by first principles and an introduction to induction. Previous assignments can be found here, but you can do this one without having done the others first.

### STEP Support - Assignment 19

This module introduces the small angle approximations for $\sin \theta$, $\cos \theta$ and $\tan \theta$ and asks some questions about coordinate geometry. Previous assignments can be found here, but you can do this one without having done the others first.
