Forgetting Japanese D:

Started doing some worksheets this evening only to find that I have forgotten most of the grammar points from lesson 4 and 5 :( I don't have many opportunities to practice using Japanese, and for some reason, I can not recall how to form sentences properly when I want to speak them aloud. Then I decided to see how far along I am in my progress to see if I am near fluent enough to do the JLPT 5 and I got most of the questions correct but there is still a way to go. I think starting from tomorrow I am going to do what I said I would do in my first post and practice my grammar by writing a short paragraph about my day in Japanese.
