Con Should be used along with another course/book
InternetPolyglot states on their site that the program is meant to aid in memorization only, and should be used along side other resources.
Con Games do not end on their own
You have to decide when you've had enough playing the games, or set a timer. The games do not end the game for you, so it's not smart about conserving your energy or ending the session when you've learned the material or when you've gone beyond 25 minutes which is the limits of most people's ability to focus.
