I like the variety of lessons. All of the lessons involving spoken Spanish are helping me with my biggest weakness, which is understanding Spanish when it is spoken.
I do have one major complaint, and that is that more effort should be put into giving a more accurate and useful English interpretation. The addition of an exact literal translation would both provide lessons in the word order of Spanish, and also help with learning new Spanish words. All too often I am wondering if this word that I have been introduced to before has a new meaning, or does it just look that way due to the interpretation being based on what a sentence means, and not on what it actually says. (e.g.: "me gusta" means "I like", but it literally says "me it pleases")
