Title: Learn Japanese From Some Guy: Quickly and Easily Master Beginner and Intermediate Level Japanese Grammar. Autor: Jeremy Rasmussen Available in: Amazon.com kindle Last year. I got this free full kindle version during its release when I was into intermediate level japanese study. Content wise, the ebook provides fairly clear, beginner friendly grammar, hiragana and katakana explanations, backed up with multiple simple examples followed by a serie of simple exercises that help to reinforce the newly adquire grammar rules. Is meant to give a good grasp of japanese foundations without delving in convoluted explanations behind every grammar rule as some traditional books do. Therefore, is not good enough study material if you're looking forward to take N2 Japanese proficiency test or higher. But it is good enough to cover the basics. But the thing is that there are already free alternatives such as Tae Kim grammar guide. Although Jeremy's book is more straightforward and easier to understand compared to Tae Kim's work. To summarize, is a pretty decent book for its target audience (beginner and lower intermediate japanese students), and is not a poor choice at all for just 8$, even compared to free material.
