Is there a difference between theses sentences?

[Offroad]

Hello everyone,

I was wondering... Is there a difference between these following sentences?

FATHER: So, teacher, How's my son doing on english learning?
TEACHER: He's doing good so far.

Or should the teacher's said:
TEACHER: He's doing good up to now.

So, question is... "so far" and "up to now" have the same meaning at all?

Thanks in advance

They don't have quite the same meaning. In fact, if the teacher had said 'up to now' he will have a specific complaint to air with the parent about the child's learning.

'Now' is implying that something has happened, whereas 'so far' expresses a time up to the meeting in which the child's good learning has continued and is not necessarily going to come to an end. Even in this situtation, the teacher is reminding father and and son that good work must continue!

By the way, I would choose the word 'well' instead of 'good'.

Thank you for your answer, but, one more question... you said you'd use "well" instead of "good", so, is it wrong? unusual?

and would it be right if I had said:
Don't worry father, your child is doing well until this moment!!!

I mean the child is a good learner and he has doing well all the time, but I don't know if he'll do in the future.

So, could you guys give me an explanation on this? I apreciate every comment in advance.
Many thanks.

In the examples you gave, 'Good' is an adjective, but 'well' would be a better word to use because it is an 'adverb', i.e. it describes how the boy worked. To clarify:, you could also say 'the boy did some good work'

'Until this moment' still sounds like something has happened that has ruined the child's good form!

Ok, I got it about the child's work.
I've read somewhere a native speaker wrote "He's doing good", well, it sounds ok to me, but you're right, "well" sounds better!
Thank you for you time.
