Shall I Burn The Book?

Hi guys, long time no see. How are you all doing?
Guys, sometimes I hate myself. and right now, I'm HATING my self sooo deeply.
I just bought a book last afternoon but then I realized that it's been useless to buy book now since the UGM entrance will be held in not more than 2 weeks. Hahahaha. i really want to burn that book. But I hold it, who knows that I can memorize its materials in one week?

What makes me more regret is, that its contain cant be understood very well. it's too simple, I know it's just a summary but I mean.. Pleaaaseee,, they're too short!
Oooh, I really want to burn that book.

Shall I burn that book??
