What specific classes are you taking in the fall? When do you plan to apply? One of the biggest misunderstandings students seem to have on here is what schools can see with regards to fall classes. If you apply in July, even if schools don't start looking at applications until November, those fall classes are still incomplete (and aren't verified as in progress). If you apply to a school who considers applications starting in January, then you can use the December academic update to update your fall classes.
I think you will get better answers if you list the exact course plan here.
One more consideration....if you have a low GPA, you absolutely need to have as many of the pre reqs done as possible. Don't let the school "guess" that you will get low grades in those too. If you have straight As, then I think it's fine to have pre reqs outstanding in accordance with school guidelines.
