Keep your mind sharp and test yourself every Friday with a brainteaser email from Credo Reference. Credo is a new online service we provide from the reference section of our website, a searchable box that works like Google but brings you results from over 300 reference books instead of the web (instead of hunting and hoping the information is accurate, you’ll get immediate answers from reputable sources.)
You can see some sample questions here. Sign up and start thinking!
