Mark, Welcome to the Chrons!
Personally, I was mesmerized by the defenestration, but I was hooked at... well, I'm not going to say because I don't want to spoil it for anyone.
I'm glad you're excited about the story! I'm glad you're reading like crazy. I don't want to rain on your parade... but let me add a couple of caveats...
First, beware even reading the names of threads in this forum! Thread titles can give away major plot developments. Avoid any and all threads that have the words "spoiler", "beware", or "theory" in the title. Many of us have read all five books to date and often mention things that you should not know. You should enjoy your own first impressions rather than just start believing our wacky theories. Some readers take the story at face value... and some do not. Read the story and make up your own mind before you begin to delve into the loonier posts... This link is to a thread that backs up my point.
WARNING! This board is full of spoilers!!
Second, don't get so hooked that you neglect your school work.
Third, enjoy the story. Savor it. ArstenWhitebeard mentioned in the above post that it takes a while for Mr. Martin to finish a book. I read AGOT and ACOK in September 2000. I only had to wait two months for ASOS. Since then, I've waited fourteen years and five months... for AFFC, ADWD, and now TWOW which will hopefully arrive in bookstores in 2016... but you never know. So enjoy the ride! Don't get caught up with the impatient jerks living on vitriol and venom.
Fourth, don't neglect your studies.
Fifth, do not shirk your homework.
And let me also state that the first five threads in the GRRM forum should be safe for you for you to read. Ursa started threads for each book that are supposed to be spoiler free, eg. without reference to further books in the series.
A Game of Thrones - NO SPOILERS PLEASE
And by the way... please do not click on any threads titles that resemble a mathematical equation.
