The rainy season has started. Wet books can easily turn into moldy books so here are some rainy day tips:
* don't use your book as an umbrella
* don't leave your books outside (even in your backpack outside)
* if you are walking/ biking/ skateboarding in the rain or have your backpack outside during sports practice, wrap your books in plastic
* if your book gets wet, fan the pages and dry with a hair dryer or other hot air source
A moldy math book will cost you $60 - 100 to replace so "an ounce of prevention is worth a pound of cure".
