Microsoft Visio has a good range of electrical components even in the standard package. You can get an academic version pretty cheaply (£26 ex vat from Viglen). The advantage of Visio is that you can use it for all sorts of other graphics. I use it all the time at work, and when you get used to it, it is really powerful.

Alternatively you could download the free trial version of ICAPS from, this is a full spice programme but has a nice graphical schematic builder that will allow you to build and model circuits with up to 20 components, that I assume would be more than enough for 11-18 year old circuit analysis.
