What loans should I accept on the EFAN notification? (UCLA)

So I’m looking at my efan notification and I have been offered grants as well as about $10,000 worth in loans. My main question is how to know how much in loans to accept if we haven’t received billing yet? I have been trying to estimate it based on tuition cost, cost of housing, as well as estimating how much $ in books (I estimated about $1300). The only thing is that we won’t know until we find out how much everything costs altogether. Should I click undecided on the loans section? How much time do we have to accept or decline financial aid? Any information is appreciated and helpful, thank you!

Which school?

Sorry I didn’t know where to put it. UCLA

This is what I used to estimate FEES ONLY

And used this as an estimate for other expenses

And then I factored in any more housing payments I’d have to make. Remember to divide things into threes, since FA gets disbursed 3 times an academic year.

Hang on, I forgot to mention that health insurance is counted in both the ‘other expenses’ and ‘FEES ONLY’, so also make a note of that
