D in "elective" over a Winter Semester, admission effects?

Need to ask this very quickly, but what effect would a D in a biology course (4 units) taken over a 6-week winter course have on my admission status?

Keep in mind, I have around a 3.2-3.4 GPA and already completed my A-G in science at my High School (I’m in a “Middle College” program, taking college classes Junior and Senior year), and my major is Mechanical Engineering/English. I’m thinking that, because I already completed the A-G’s for science and took the class for an AA. I had a lot of trouble with that class as I didn’t expect such a mix of chemistry (which I’m worse at) and biology, as I cannot keep track of some of the terms very efficiently and did my best but still failed with, what I think, is a high D.

Is it a good idea to let them know of that D and perhaps retake it in the summer? Or simply let them know just for the sake of it? I’m really worried. I applied to UCR, M, I and CSUF, LB, Pomona.

If you took a college class, you will have to report it. Talk to your guidance counselor.

Middle College is a program where I take my high school classes at the local CC, so no need for that.

What I’m wondering is how bad this D is? I’m reading that the opinion is all over the place; some say a D is the end while I read another that stated, because I already took Biology Honors freshmen year and passed that, that this class was “excessive” and so wouldn’t affect my A-G, only my GPA.

For the UC’s, you are required to report any D or F grades after your application is submitted.

Freshmen: If you change schools, add or drop a course, or fail to earn a C or better in a course after you submit your application, you must notify the UC Application Center by email or postal mail. Your correspondence must include your name, UC Application ID number and your signature (if you mail a letter), and will be available to all the campuses to which you applied.

If you receive an offer of admission, be sure to confirm with the campus admission office that they are aware of the deficient grade or schedule changes. Although you must notify the campus of these changes, we cannot guarantee that a campus can go back to review an application after correspondence has been received. Make sure to save a copy of your correspondence just in case.

Most Cal states require that you pass any a-g courses with a C or higher to maintain your provisional admission. Speak with counselor and contact the schools. Better find out your options now then in July when your final transcript is due.
