The trouble of learning a new language...

I have been residing Belgium for almost a year and it just doesn't make sense that I can't understand French or Dutch. So, I told myself "Cindy, you gotta learn a language before you leave!" After a few consults with friends, I decided to learn Dutch. So today, I was browsing at BBC and learning the basics of Dutch and stumbled across a website that helps you learn Dutch. It shows you videos with Dutch and English subtitles. So I told myself, "Not bad at all.."
Then, I saw Sesame Street and told myself, "Okay, this would be easy. I know you hated Sesame Street when you were a kid because it's just so slow! But this will let you learn the basics." and Click... and this is what I understood...

Ja, ak? ik? bla bla bla Bert

Nee, Nee, bla bla Ernie

Bla Bla bla Bert

bla bla bla Ernie

which translates to

Yes, ak? ik? bla bla bla Bert

No, No, bla bla Ernie

Bla bla bla Bert

bla bla bla Ernie

and so what did I understand? Nothing, they talk so fast! I only got Yes and No, Bert and Ernie and practically Bert, Ernie, Bert, Ernie...
*sigh* This is so difficult...
To add, I'm enrolling myself in a language course and I have to take an oral exam, so how do you take one if you practically don't know anything besides Ja and Nee... Hmm..
