Is any one memorizing the BSM equation for Call price

Hi, I have not memorized the Black Scholes model. Is it necessary to memorize this for the exam? We can derive the answers to many questions by using the Put call parity equation. I surely will appreciate your responses.

The text clearly indicates that we do not have to memorize the BSM. Just understand all of the various inputs. Put-Call Parity yes BSM no.

Yea, it’s pretty much black/white in the text that you don’t need to know it.
