@goldencub, I’m not exactly sure who was writing each letter. (I think CCC counselor in first and UCB in second?) Anyway, this has been brought up a lot lately and my understanding is:
(a) Definitely 100% you will get IGETC-certified as the CCC makes the sole determination on that and the UC honors it. This part I know is accurate.
(b) IGETC-certification, indicating fulfillment of the English requirement will fulfill the requirement.
© I believe you will still get unit credit as any exam over 3 gets credit.
This is my understanding, but I might be wrong.
