Why I study Japanese..?

I lived in Tokyo for one year when I was very young. Since high school, most of my Japanese knowledge was learned from Japanese Anime or Japanese Movies. I felt like I need to learn real Japanese. Especially when some of my best high school friends went to Waseda University, which made me very jealous.
During my visit in japan, people did not know what I was saying, except for some basic Japanese like: How much, thank you, you are welcome, I am sorry. When I realized it's tough for me to make  Japanese friends with poor language, I decided to learn real Japanese. I was self-studying for one year, but already forgot most of them. At beginning of this semester, I did not even pass the placement test to second year Japanese....neither elementary Japanese B. So I wanna review all my Japanese language, and make progress every day;)
