word,word,word

Today, I have a class, and it's a first class, so I almost free today! I thought today what I do, and I decided to study. I should do "power words". This is software to learn words in English. I didn't anything, so I tried from unit 1 of level 5. I should learn from unit 1 to unit 15 in May. I was going to learn from unit 1 to unit 5, but I learned from unit 1 to unit 17, so I could finish my subject. There are a lot of word in my head now. I don't want to forget it.
