So far the program has been quite good. However there are a few drawbacks.

First, instruction. For example, it says that when greeting.. "sa iyo" is used for people around your own age, and a few exercises later, it introduces "sa inyo" explains that it is also used to greet people.. then later says its used to greet people "much older than you". If you forgot specifically that "sa iyo" was said to be used for people your own age, and then hear "sa inyo" introduced.. it wouldn't be too clear which one you should use when.

Other than that, again excellent program. Looks like its laid out well, and besides the few drawbacks, so far so good. Can't wait until I'm fluent. :)
