Honestly it may be worth it to take the leveling courses in CSD. That's what I did and, and tried my best in those classes. Then I applied to schools that mainly look into the CSD GPA and last 60 units GPA. Look at my stats, they aren't very fantastic, but I got in. I was able to redeem myself with my CSD GPA, therefore they overlooked my overall and first degree GPA. I agree with the poster above, ask the schools what the stats are for their accepted students are, how many applicants they get, what parts of the application they weigh heavier than others, and ask them what you can do to improve your chances. Hope that helped
