I picked this up for 3 reasons: I really need to practice my reading; The premise sounded interesting enough; There'll be a movie (release date: 2015, May 1st).

The story is told quickly. Sayaka is a 17-year-old Gyaru with bleached hair, short skirts and lots of make-up. Her 学力偏差値 (average score at standardized school tests) is 30 (out of 100), she's worst in her class. To make her mother happy she starts visiting a cram school and notices herself that her level is so low (her English is on elementary 4 level) something has to be done. Over the course of the next year and a half her level improves so far she gets into Keio University, the oldest school for higher education in the country.

So far, so obvious, the ending is in the title.

However, the story of Sayaka's circumstances, her family and the change occuring in her, is nothing short of extraordinary. You really get a feeling for how her special personality, the support of especially her mother and her cram school teacher, and her astonishingly hard work have made this possible. In a letter to the reader, Sayaka urges us to not think that she was special to begin with - everyone can do what she's done. It's really one of these books that make you want to get off your arse and get things done. :)

I first read this book when I was in 6th grade when it was very popular and I recently watched the movie of it so I wanted to reread it. It is about a girl that went to a good private middle school/high school where she can just get into the college, and she starts to mix with the wring crowd and starts to fail in school. She is a good child and sister, but she is not doing well in school. But one day her teacher calls her a failure and that she won’t even get into their college, and she decides to study hard with this amazing coach and eventually gets into Keio University. This book is really motivating and it is fun to read because the coach and she have a really nice relationship and have a lot of fun. I recommend this book to anyone who needs to be motivated, especially in school.

I picked this up because it seemed not too difficult to read for my level, but still difficult enough to be a challenge.
There are some chapters where learning methods are explained, I ended up skipping a few because they were too complicated to read and not that relevant for me anyway.

この本を読み、不可能だと思い、諦めかけていた事も自分や自分を支えてくれた人を信じて最後まで頑張り続ければ可能に変えられるという事が分かった。
