There is a three modifiers in the abstract abstraction.
This week the feeling of difficulty increased, the case also integrated before the beginning of what has been learned, in short, no longer feel relaxed, but I found myself knocking several times, you can find a good understanding of the content of the teacher to explain. There is now the time to encode, it really is focused on the principle of low coupling, some packages show no advantage in less time objects, but a comprehensive case to be able to feel it.
Now the stage, I can not feel afraid slow, a timely review previously learned knowledge, knowledge to prevent fracture of the back.
