Cal Grant A vs. Cal Grant B

<p>I was awarded with the Cal Grant B and I accepted it, I went back about a month later to check on my financial aid and I was notified that it had been changed to Cal Grant A.
Cal Grant A gave me more money but it also caused my UCR grant to be slashed in half.
At the end of the day I was left with a couple hundred less than my original award.</p>

<p>Has this happened to anybody else?
Why did my grant change?</p>
