Tag to UCR but only applying to UCR (Essay Question)

Major: Business Administration

GPA: 3.62 (Probably will end up with a 3.7ish GPA)

So, I tagged to UCR but it’s the only UC I’m applying for (I originally was planning on applying to UCI, but I took business calculus instead of the 2 regular calculus classes). Does the essay I apply with have to be any good? Considering I’m already guaranteed admission into the school if my TAG is approved.

No.
In addition, UCR doesn’t even read the personal insights as part of the regular admission application.
