Hi, I'm totally new to this forum, and because I been learning Japanese by myself for almost 2 years using Minna no nihongo, so i decided to join a forum now.
I been having problems with particles too, but I know a site that give very good explanation, until I finally understand the particles + all the v-te form, v-ta form and etc, if you don't mind I can send u a pm of the link.
p.s: because all I did is self study, so hopefully the site will help u too.. because is very easy to understand it.
