Do UC's Consider Rigor of CCC?

Hi so I go to De Anza, one of the 3 California CCC’s on the quarter system and it is known to be a harder CCC. It also does the +/- system which I recently figured out not all CCC’s do. I was wondering if admissions consider that to try to make it more fair between the schools? Do they consider rigor of the school? I had 1 A- and it honestly tanked my GPA so does anyone know if they essentially see the A- as an A?
