While I initially trained on Penton Intl, I also took this program... the testimonials suggest Thomas' approach is well thought of.... I can vouch for that - Michel's expertness is beyond reproach. Thomas focuses less on memory and more on 'why and how' particularly on verbs and verb forms often making logical comparisons to English. Instead of listening to fast speaking dialogues that you need to replay 5 or 10 times, he has you thinking slowly about what is being said and the correctly formed translation. The two new students have you in their court as you listen to an unusually powerful lesson. Simply the best I've ever heard. These are in never used condition - even the case still appears new with minor handling scratches.
