This is what I guess.
I have an opportunity to talk with English speakers.
First, I have to say that English is not first language for them and I am not bilingual. So, my guessing may not be correct.
The difference between "will" and "be going to"
WILL contains will."BE GOING TO" sounds like "BE SCHEDULE TO".
e.g.
I will be there on 6PM.
For me, this means "I want to be there on 6PM"
I am going to be there on 6PM.
This sounds "My schedule is being there on 6PM".
If somebody help me to wash my dish and then he says,I will do it.
This sounds "Let me do it instead of you".
This expression could not be "I am going to do it".
I am not sure if this is correct. But I think there is the difference between two of them.
