আমি বাংলা জানি না৷
aami bangla jaani na.
I don't know Bengali.Wow, Bengali is quite fun to learn. I wish there was a native speaker to teach it, but oh well. I'm still going to learn it anyways...in addition to the 3 other languages I'm learning.
Yeah, so I actually tried to find the site you were talking about for teaching yourself, yet I didn't know which one it was. Could you tell me which one it is?
Also, I found this source to be quite helpful in my opinion:
