I bought this for myself to use on my son's DS Lite to brush up my school learnt French some twenty odd years ago. It tests you at first to see what lesson to start you on.
You read about how to write French and translate English into French before inserting words into sentences, find words in word searches, hit moles on the head that have the right word wrote on them and answer multi choice questions. The words are said in French which helps you to hear how you should pronounce it.
Each time you do a lesson or a game you are awarded points, when you attain enough points, ie show you understand the words/lesson the next lesson opens up.
This is a fun way to brush up on French or to use an ancilliary aid for the kids learning French at school. I would definitely buy it if my sons were in secondary school or even in primary to give them a head start.
I definitely recommend it for those wanting to learn a language, brush up on a language or for kids to help them at school. The main thing it is fun but you are learning at the same time.
