UCLA Engineering Essay/Pre-Reqs? (Advice needed desperately)

So I applied to UCLA as a chem major, but I changed my mind and I wanna change my major to chemical engineering (UCLA lets applicants change their major until 1/3. I have 4.0 GPA and I think I can rush all those engineering pre-reqs by spring (physics 2, physics 3, o chem 2, and one programming course left)

But the thing is that on the application essay I wrote about chemistry major and not chemical engineering. Would this affect my acceptance? I heard engineering school doesn’t really look at the essay but I’m not quite sure. Does anyone know about this? And can anyone advise me whether I should change my major or not?I only have like a few days left to change so I am desperate.
