Library classes

I have library classes. I had 2 classes in spring term. I have 4 classes in autumn term. I had 2 classes when I’m a freshman. I be studying ‘NDC’. NDC is Nippon Decimal Classification. It was usually used for classification in Japan library. I study it in one librarian class. NDC have from 001 to 999. Moreover It sometimes stick some number. It have each classification rules. I study about 160 problem in winter vacation. It is very difficult for me. I need get 12 credit. I do my best.
