1) Not really. It really depemds on the material and the teacher. In my case, I am visa versa about it cause my teacher is perfect, he really teaches us history, he contributes his soul in every lesson, he carries our minds in every period we learn. But it is very complicated for me. My brain is not made for remember that big number of days and actions, unfortunately.
2) From every sources of information. For example books, internet, people, every note that is connected with history can cary a lot of essential information in it.
3) I believe in a theory that the time is cyclical. That everything that had already happened will happen again. Maybe in another form but still we can divine our future, am I not right?
4)  If people always learned lessons of history this world would be perfect. In fact, it is not and it is not going to be. We have to be realistic. Hope for best but plan for worst as I always say.
