How Do I Learn Japanese

I speak four languages including Mandarin, Cantonese, Japanese and English. Today I am going to share my experience of taking notes for Japanese learning. And I had passed N1 test within one year from zero. I am going to share my experience of taking Japanese notes.

What Notebook Do I Use?
First of all, a nice notebook is necessary‌. I prefer a A4 or B5 size leather notebook as I love to have more information in one page. I test notebook before I know my preference.
I used A6 notebook to take notes at the beginning but I found it annoying to turn page a lot with little information in one page while reviewing the notes. That's why I finally choose a A4 notebook. 
There are pros and cons for both notebook sizes. A6 notebook is easy to carry for its compact size but less notes in one page. B5 notebook is large enough for more information but too large to carry. This is what I consider when choose the notebook size.

How Do I Take Notes?
I will transcribe vocabulary and example sentences before I start a new lesson. It help me to remember them.
I write down the word and explanation on one line and sentences on next line. For A6 notebook, one line for one word, but for B5 notebook, I fold the paper in half and two words in one line.
When it comes to grammar, I write down the main ideas and example sentences for comprehension.
Then I start to learn the text. I don't try hard to remember the words but just to make an impression. It helps a lot to comprehend the text. And reading the text several times helps to remember the words and grammar.
