Yes Mario! It will speed up your learning, wouldn't be hard at that pace
It is pretty expensive but good value too. Homeschool buyers coop have it on special often enough. You will probably need a headset microphone to use it. I payed $12 Aussie for mine and it works very well. Good for making LR files too
Here is a Rosetta Stone free shipping and bonus points deal. The points are actually enough to buy something for nothing so sign up to the sight before you buy if you do.
