Naming complex aromatic compounds

Does anyone know a website with Q/A or just general help for this? I'm having trouble with compounds such as N-sub'd methylethanamine... I can't find many practice questions that ask me to name compounds.

This is for Edexcel Unit 5. Any worksheets, websites etc will help!

Thanks

Here's a little practise program. Click on the link and save to your PC. Unzip the file and run it.

Enjoy...
