Help! UCLA hold!

Hi everyone!
I have been admitted by UCLA!
I have 6 classes this spring quarter! And 5 are pre major classes! I want to drop one class and retake it this summer quarter. After I submit my academic change form! My admission status was hold! And they did not contact me for 6business days because they haven’t look it. I called them and they said I should wait.
Is there any one have similar situation? What should I do? Am I in dangerous situation? I don’t drop the class yet, but the best I can do is a C. I don’t know which case is worse! Help help thanks!!

If you get less than C you would be definitely in danger!

I think I can get a C… But in that case, I stillhavero report to UCLA

Sorry I mean still have to.
Because they don’t allow C in pre major class
