UCD to CC to another UC?

<p>Hi, I am a freshman and UCD right now and after this quarter, I have 51 quarter units. However, 24 of them are from APs so after this quarter, I will have 27 units taken at UCD. I want to go to a CC but can I do it now? Can I go back after winter quarter to a CC and transfer to a UC again after 2 years? Will i be able to transfer after 2 years at the same pace as others? Am I still eligible for TAG? Will my GPA be carried over? Sorry, any information will be very helpful. Thank you!</p>
