Learning Spanish in 10 months

[MiCasaEsSuCasa]

iHola! (I will be using an "i" as the reversed "!")

I've studied Spanish for three years in school, although I barely passed the course. The last two years of the course I didn't have any motivation whatsoever to learn the language. I didn't learn all the things that I should have learned, which is a shame.

But I have some basic knowledge of the Spanish grammar, I got a small vocabulary as well, and I do know how to pronounce the words correct (Although the double r sound is really hard to pronounce).

My timeframe is approximately 10 months. I'm going to Spain in 10 months. When it's time to get on the plane I want my Spanish to be as good as a native speaker's Spanish is. I wanna be able to speak Spanish fluently, with confidence. I want to know all the basic grammar that every other Spaniard knows. I want my vocabulary to be big enough so I can have everyday conversations without having to stop and think "what did that word mean now again...?". I'm not gonna work in Spain or anything so I don't need to learn speciallised words, like if I would work within medical care in Spain I would have to learn medical terms and so on.

Is this possible? I got a lot of spare time. At the moment I'm free as a bird. I can spend about 8 hours each day studying.

So, I got: Enough time (although I probably will have to study Spanish almost all of my free time), motivation and learning material. What I lack is a teacher. Someone who can put up a plan. Tell me what I should learn and when I should learn it.

Right now I'm using this webpage: http://www.studyspanish.com

I'm going through the grammar parts. It's killing me, really. I want to learn fast and see results immediatly, but it doesn't work that way does it.

What is the best method for learning a new language? Should I read and study every part of the grammar lessons slowly to make sure it stays in my memory or should I read every lesson one, maybe two times, and then move on to the next one?

Or, is it possible to only learn the most basic grammar, then expand your vocabulary and just speak Spanish a lot?

I'm in desperate need of help!
