Only a beginner, on the first lesson, have spent 3 or so hours, reviewing words & phrases. I'm an old dog (60) and have some trouble retaining, such as spelling and remembering odd words like articles, and punctuation, so far, makes little sense. The extra phrases are hard, so far. I expect to build on those in the future, which should help. It's all new to me now, little to build on. Program works well and is immediately accessible. Have not used customer service yet but setup was fast and went perfectly — no problems.
