JPLT N4 in July- February 21st

I finished preparing my study notebook of readings, example sentences, vocabulary and grammer from my Japanese Language Proficiency Exam N4 books. I was originally going to push myself for 3 months and try for N3, but I figure if I just do N4 my foundational Japanese would be a lot better. Also I can take the N3 in December after I pass the N4 in July. As a side note, my goal to be proficient not only in writing, reading, and listening Japanese, but also speaking it because I believe second-language stick a lot more once you learn how to speak it. I know its a lot of work but I want to gambaru and start my journey to become truely fluent in Japanese!!!
