The best books to hide under your table and read while the teacher speaks.

Tips:
-try relaxing books. If you suddenly start laughing or crying, he/she will notice.
-if you are having class of english, avoid reading in english. you can get confused.
-read a light and small book. You don't want anyone to notice
-sit next to the window, the light is better there.
-don't let it on the table before or when you are not reading. they will notice something is going on.
-read and stop, read and stop. When you stop, look up. Apart of looking like you are paying attention, your neck will hurt less
