Do I have to be good in physics?

Hi. My name is Lili, and I am a senior looking forward to chemical engineering as a major. I was wondering if you have any personal opinion about the career. I love chemistry and math but sometimes physics gets hard. Would i need to be good in physics? It is not like I am bad at it, but I am a little worried because of the engineering part... Any suggestions? I am glad I found more people interested in chemical engineering.
