[General] I have completed my schooling

[gurpreetgill4u]

Hi,

I came across these sentences and I could not understand what they mean exactly

a) I have completed my schooling from xxx school.
b) I finished my schooling from xxx school.

I suppose it should be like
I have finished my schooling at xxx school.

So basically my question is at vs from

In India schooling is used just as we use the word graduate.

I would use "at".
