understand next to everything

[englishhobby]

Are the following sentences idiomatic? (including the phrase in bold)

I think my pronunciation and my vocabulary are getting better and better every day. I understand next to everything now.

 

[Rover_KE]

'I understand nearly everything now.'

 

[MikeNewYork]

Or "I understand almost everything now".

 

[Matthew Wai]

Does 'all but' work? The Oxford dictionary says it means 'very nearly'.

 

[Rover_KE]

Close, but not quite.

YOU: 'Do you understand everything now?'

ME: 'All but.'

 

[Roman55]

I am not a teacher.

I think my pronunciation and my vocabulary aren't bad, but when I listen to native speakers I understand next to nothing.

 

[Matthew Wai]

.. getting better and better every day.

I found the phrase 'with each passing day' in the Oxford dictionary, can it be used instead of 'every day' here?

 

[Roman55]

I am not a teacher.

Yes, or you could say, 'getting better day by day'.
