Does anyone know a good source for transistor related calculation problems. A few worked examples and then a lot of do-it yourself problems is what I am looking for, prefereably with answers so that I can verify my results.

I am learning about transistors for the first time, and while I understand the basic operation, I feel like I need to really set it in with some "practical" problems.

 

Try the Socratic Project - scroll down to the section titled "Discrete semiconductor devices and circuits", you can download PDFs of worksheets there.
