Cons
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.
Con Frequently gives you a word with different translations, of which it only accepts one.
No real way to discern what you are asked to enter.
Con Sometimes teaches vocabulary out of context
Con Few language pairs available
Currently only offers English and French. The website says there are 6 other languages in the works.
Con Not enough variety in exercises
Words are learned only through fill-in-the-blank style problems. The user is not challenged enough to be able to remember and use the learned words in circumstances different from the fill-in-the-blank sentences.
