I agree, but it depends on the program bc all program standards are different. I know that with my LMC application, I submitted my app with a repeated A grade in English but after receiving the notification email in March, LMC ended up using my original B grade back from 2004, which turned out fine bc the point value was the same anyway. Delta also only takes the first attempted grade. ARC and Sac City will take the highest grade as long as the course was taken at another district. Some programs will subtract/not receive additional points for repeated grades (Sac State, Sierra) and others might average the two grades together in the GPA (Chico).
Earning a B in the sciences is pretty good considering how intense they were.
