how can I get cal grant b (transfer entitlement) ?

hi guys, I’m a transfer student. Today, I checked financial award and it shows me university grant (low covers).
I heard there is a Cal grant B (transfer entitlement and it covers a lot).
Does anyone have information to get Cal grant B?
Do I call or email to the financial aid department that I want to change university grant to Cal grant b? or do I have to do something else?

Thanks

You have to be eligible for the grant.
Did you fill out your FAFSA?
Is you income within the boundary for aid from Calgrant?
The Calgrant office selects the type of aid you are eligible to receive based on grades and income.

Forgot to ask: Did you graduate from a California high school and have you been a resident of California?
