This is the most important unit there is. In the following ten lessons you will learn how the French language works and you will even learn how to think in French intuitively. After you actually start thinking in French, learning vocabulary will not be much of a challenge. The most important thing to keep in mind is to start thinking in French and the rest will follow.
You may want to watch lessons a few times, or maybe one time will be enough for you. It doesn’t matter, everybody learns at their own pace and some lessons might be easier for one person while other lessons might be easier for other people. Keep in mind, you are not obliged to learn every single word and rule on each lesson. It would be great, and if you do so much the better, but do not get stuck with the goal of learning everything perfectly. Your goal is to keep on moving head and learning as much as you can within reason. Good luck, and enjoy your lessons.
