Dear ! Colleague

I have joined this website for 5 months. Recently, I have created a page that can help both Vietnames and other students in the world. The main purpose of this page likes a bridge where students and teachers can discuss , share what they do not understand or what problems they are trouble in. I �m appreciate to everyone take a look the page in sometimes and post your exercises that you have used them or give your comments,advices on student �s answers. 

Here is the link: https://www.facebook.com/groups/610424135826767/

Thanks in advance.
