I need to find some masters-level exercises about numerical methods for solving ODEs. Are there any good references? 



Any good books on numerical methods for ordinary differential equations? 
Since nobody else has mentioned them, I will recommend [**Solving Ordinary Differential Equations** (volumes I](http://www.springer.com/mathematics/analysis/book/978-3-540-56670-0) [and II)](http://www.springer.com/mathematics/computational+science+%2526+engineering/book/978-3-540-60452-5) by Hairer, Nørsett, and Wanner.
