Garbage! Against the Exchange, if 4.Nc3, Black should play 4...Bb4, not 4...Nf6. 4...Nf6 works against 4.Nf3, not 4.Nc3.
Also, if 1.e4 e6 2.d4 d5 3.e5 c5 4.dxc5?!, Black should play 4...Nc6!, not 4...Bxc5
What are you rated, like, 1200 or something? Your knowledge of the French is clearly lacking, and before you try to return the question, I have played the French Defense probably over a thousand times over the board. Somewhere around 50 or so times, give or take, as White and the rest as Black.
