<p>You can take classes to make up the D’s at BYU’s online high school program. My son did it for one D and it brought his GPA up by .6%. If you could do it for 3 D’s it would help a lot. BUT the Cal State apps are up today and close November 30 so you need to do it pronto! If you bring up your SAT by 100 points or so it would make a huge difference and you can retake through December. Good Luck!</p>
