Translation of Kristallnacht

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
Take your time to answer me, do the vocabulary exercises and measure your progress! Your answers will be kept in the system itself. After that you can look at the statistics. That's pretty cool here.
Thank you for correcting my mistakes. I am really grateful for that and this is exactly what I wanted, I just think about whether something similar exists also in English. I doubt it.
