ReviewNet has posted a SQL skills test that you can use to review your SQL abilities. Here is the announcement they sent the group:
"ReviewNet would like to extend an opportunity to your user group members to take our new SQL Server skills tests to evaluate their skill level. Individuals that complete a beta test will be credited as an advisory panel member on our website at http://www.reviewnet.net/meetexperts.cfm. Individuals receive their test results and can see where their skills compare with other test takers. Participants also qualify for our Advisor Rewards program and a chance to receive quarterly cash prizes. You can learn more by visiting http://www.reviewnet.net/advisor.htm. I would like to extend this opportunity to you and your members."
