Argentine Spanish?

Hola a todos :)

As you might be able to tell, I'm a new kid on the block, but I have a question I'm pretty sure y'all can help me with, which is as follows;

What are some of the key differences between the Spanish I'm learning on the RS course, and Spanish spoken in the BA area of Argentina? 
Main reason I ask is because my girlfriend is from BA ;D and when she speak Spanish you really pick up some of the subtle differences - pronunciation, 'Vos' etc etc 

Is there any key information I should bear in mind whilst on this course, or is it information that I will pick up as I go along? Any tips and tricks for my independent learning?

Cheers a bunch in advance!

I am told that the accent in Argentina is very strong and can be difficult to understand. In fact, my language speaking partner who lives in Spain has been there and says she has trouble understanding them. Other than that, I imagine they have country-specific words like most other Spanish-speaking countries that are probably only learned by going there or having a speaking partner from there. But it sounds like you have that covered!

As to your other question, just general good advice: study every day, work on increasing your vocab and learning the grammar, use sources outside RS such as Yabla, and make sure to spend time on all 4 aspects: reading, writing, listening, and speaking. And have fun.

 

One of the things that I've noticed is that the "double L" and the "Y" sounds can both have a very pronounced  "J" sound to them.   
Also (and I'm not sure about this), but I think the Argentinians also use the familiar "vosotros" conjugations.
