In September, I have relearned chemistory of the high school level.I used the 360pages book I had used before
about 30 years. Especially, it was useful for me to understand the little part fo organic chemistry.
Though it took about 2 months for me to read the chemistry book since this August, I was happy to understand
a little chemistry I had been not fond of.
