b. Reading course is interesting, but it is also difficult for me too. Especially, I'm not good at typing sentence with listening English. I want to type precisely in first listening.
c. I learned some of new idioms and vocabulary. I could spell words which appears in unit 2 correctly.
d. I realized my reading speed is so slowly. The first aim of reading is to read on 120WPM. I'm going to study this course more. I have to study not only in class, but also in my home. I will do my best to acquire English skill.
