What I keep seeing in this thread: "Learn from anime! hurr hurr!"
DO NOT DO THIS!
Most anime uses incredibly casual Japanese language, sometimes rude language, and lots and lots of slang. NOT the best way to learn, especially if you have any inkling of the "hierarchy" in Japanese society (i.e., you use different language depending on whom you are speaking to).
Let me give you an example, the different "levels" of how to say "___ is reading a book," from most formal to least formal and rude:
hon wo oyomi ni natte irasshaimasu (most formal and polite)
dokusho wo nasatte irasshaimasu (next level down)
dokusho wo shite irasshaimasu (next level)
dokusho wo shite imasu OR hon wo yonde imasu (neutral and formal)
dokusho wo shite iru OR hon wo yonde iru (informal)
hon wo yondeagaru (super-informal and rude)
As you can see, there are maaaaany many levels of politeness in the Japanese language, and anime usually only ever uses the last two or three levels (yes, there are some characters who use super-polite speech, but they are rare and far in between). So unless you want someone thinking you're pretty rude, DO NOT copy anime.

<-- people who say "learn Japanese from anime" make me want to do this. ^-__-^;;
Your best bet (after you *ahem* learn how to speak English properly *ahem ahem*) is to take a class. And if you have "all F's" as you have previously stated, then I honestly don't think you have the dedication it takes to learn any non-native (to you) language, let alone one as complex as Japanese.
People give me headaches...
