kgcole, another one advice, if you allow. What a dictionary do you use? It's very important to use a proper dictionary. Maybe you even don't understand how much. I mean a dictionary which contains a lot of context examples. So, you can choose the right one. Because as I can see, you very often select wrong words from the list. For example, "учение" instead of "обучение" and so on. When you investigate the word and its context, you learn a lot from the examples.
