Too long stuff  aboutLong article on learning a language ^^

Group classes vs Individual classes (Have you got a suggestion?)
Here, in Argentina, we often start going to a school from a very young age. If not, we learn English at school. Perhaps we wasted over six years in learning English, but have we learnt enough?
I guess that the most of the population didn’t have english that is considered in a remarkable level and their english knowledge did not improve as the years went by . Many cases don’t show it, but we’re not going to focus on them.
One problem that I’ve detected at school was the lack of motivation. It’s because the standardization of the classes that we used to assist. Here is the thing: We don’t share the same interest and if we learn English using a book that we probably don’t like we’re going to loose our motivation. With one on one classes, you can learn whatever you want. With group classes unfortunately this is not the case.
If you decide on learning english by yourself try to focus on the things you like. I usually listen things about economy, even if I don’t have the ability to understand it. But I am not going to give you advice on this because I am not an english teacher I just like learning new things I could have been learning spanish now but instead I prefer english. 
If you learn with group classes, suggest to your teacher (or professor) a topic that all of the students agree on that it is relatively interesting (or at least, a bit interesting).
So please, don't get bored! It's really tough to learn the things you don't like.
PS: Take account that this note is for improve my writing, I'd like to expand my vocabulary :P. But, what do you think? I would love to listen to your opinion :P

well done I tried to correct your essay. It would take a long time to highlight and all but I am sure you will see where I corrected it! :) 

Ways to promote your business,2nd part

Among the advantages of social networks, it should be highlighted that they provide business with a complete interaction with customers, which is truly beneficial for both of them. Customers give feedback information that allows companies, and sometimes forces, to improve the quality of their products and keys gives an opportunity to meet their customers’ needs. As it seems e-commerce is the future, hence your company has to getting used to selling their products, providing information and dealing with customers online.
Taking all this these ideas into account, and despite the fact that you cannot avoid the traditional advertising, launching your publicity campaign in the Internet and social networks and it is worth it, and is almost compulsory to do it.

Your sentences are too long. You should try and shorten them that is how you are going to reduce the amount of mistakes you can make. The trick is to keep the sentence short and simple. Do not sugar coat your sentences with a lot of descriptive words or classify your ideas with a comma it makes it even harder for the reader to keep interest on your article. Rather keep it short and simple. 

well done! 

both of them mean the same thing but second version sounds much better
