The thing I like is you can take online and get immediate test results, rather than waiting a few weeks for results mailed/faxed in. Really? The test mentioned you may only take Wizard once w/ perfect score 'for those that need to know it all' and must be taken at the time, if you pas MSA, of MSA test.? I got perfect score so I don't know if you're allowed to miss any of the 25 questions or not? They're not difficult (not to say a couple aren't tricky) and some answers can be found in booklet (may not take w/ DVD version they say) where most are based on your own knowledge after reading/watching shingle applicator manual/DVD.
