found the material very helpful - although there was a lot of material covered - the pace was well set. Would definitely recommend people to have explored Microsoft Access beforehand to be familiarized with the program before taking the course. I would imagine someone without any exposure would find it confusing. Environment really good - people very, very nice and helpful. Would definitely take the next level of access with the same training facility.

I was not in the physical classroom. Feedback centered around online training would be good because now I have to rate items that I was not present for. Those items are getting half a star because I was not there to rate them. The course material must go through an editing process. There are a lot of grammar mistakes, but also a lot of actual procedure/activity mistakes.
