What are the options if you pass the chemistry class but failed the chemistry regents?
What are the options if you pass the chemistry class but failed the NY regents?
I failed the chemistry regents and I heard from a senior that if you pass the class, you don't have to take the regents. Is that true? What diploma would you get? Is it better for me to take the regents over again? Are there any other ways to gain back a advanced regents diploma since I failed the chemistry regents?
Only serious answers please.

That's not true at all. Seniors don't have to take the regents. However if you failed, you need to take it in august.
