ciao, sono the Prof, sono inglese e scrivo da Londra.
I know & I know it sono diverse!
I know = sapere qcsa., si usa per dire accordo di quello ha detto tu.
I know it = conoscere o capire qualcosa (ma non qualcuno, che dev'essere I know him, her etc)
esempi:

B: I know!

B: I know!

B: I know.
A: Stuttgart is a wonderful city.

A: There is a new bar in Jermyn Street.
B: Yes, I know it ( = I went there last night).
A: Do you have an exam on The Merchant of Venice today?
B: Yes, but don't worry - I know it very well.
OK - piu difficile!! Tutti due:
A: German is a difficult language
B: I know! I don't know it at all.
Vedi la differenza?
Good luck, guys, and Keep Practicing!
