Here are a few strategies for finding good questions:
1. Use the guideline filter in the upper-right hand corner of the Available Work page.
2. Set the answers-per-page to 100.
3. Skip to the middle or end of the question pool using the page filters (you don't need to complete the questions in order)
4. Use your browser's search function to look for questions with specific terms that you're interested in (usually 'CTRL+F').
5. Use the Preview button over to the right of the each title to view the question before checking it out.
