I have graduated in B.A but I have more knowledge than you.

[tufguy]

1) I have graduated in B.A but I have more knowledge than you.

2) I was graduating in B.A at that time. (I know you have told me that we should say "I was trying for a degree in B.A but is it correct to say this?)

 

[tufguy]

1. I graduated with a BA, but I have more knowledge than you.

(I fail to see the connection between the two clauses).

2. No, it is not correct to say that.

Can we say "I graduated with a B.A degree"?

Yes, but 'degree' is superfluous.

Can we say "I graduated with a B.A degree"?

I graduated establishes the academic context in which B.A. is a degree. Including the word "degree" adds nothing but dead weight to the sentence.
