Will Withdrawing get me Rescinded?

Hello all,

It is my 2nd and hopefully last year at community college. I am an Economics major hoping to transfer to UCD, UCSB, or UCB. One of the major courses is applied calculus 2. I currently have a C but no longer want to deal with the class as I fear I will fail the next couple of midterms and final.I have heard that I can take the class after I transfer. I have contacted a UCD representative and was told that withdrawing from the class does not matter as long as I still meet the TAG requirements of not getting a grade below C and having 60 transferable units. However, I am still very paranoid and do not know the proper steps to take after withdrawing the class. Will I have to submit another TAU or contact each school individually? Will my admission chances lower or get rescinded after taking a W on my transcript during my last semester?
