In the third year, there are 35 lecture courses, and a computational project. As in the second year, students decide how many courses to take: usually three or four a term. Again, there is no fixed number for examination purposes.

At the end of the year, there are four three-hour examinations, and reports are submitted for the computational projects course.

## Examples of course topics

The courses include some whose content may be guessed at from the titles, such as:

**Number Theory**;**Coding and Cryptography**,**Mathematical Biology**,**Cosmology**,**Logic and Set Theory**,**Principles of Statistics**,**Waves**

and some whose content remains obscure unless you have already encountered these topics:

**Galois Theory**(advanced group theory in which it is proved that you can’t in general solve a quintic equation);**Algebraic Topology**(in which properties of similar shapes - such as doughnuts and teacups - are classified);**Asymptotic Methods**(how functions behave at large values of their arguments);**General Relativity**(a theory of gravity);**Stochastic Financial Models**(how to predict unpredictable markets).
