Finished Powershell IAMOL -any websites for questions/labs

As the title says I finished powershell in a month of lunches and liked it, I have never done any sort of scripting /programming so I found a few parts difficult and are still a bit patchy, I found the best way of learning was to try the labs at the end of the chapters, so to get a complete understanding I feel that I need to keep on using it and get better with practice, are there any good websites with similar level / difficulty to those in the book, preferably with explanations in case I don't know how to do them and can learn? I have a home lab setup so practising is fine, questions would make it alot better though.
Thanks
Thanks
