Google Custom Search: Made By Students

Any assignment you have, try searching using this.

Basically it only searches sites which Jaga and a few others have told the search engine to.
If you are getting junk (IE non academic) from google, try this. If you want to add a site mail me and i will add you on to the contributor team. I dream about the whole of PV adding good sites and eventually we have a seriously killer search engine that delivers only relevant academic results.
