Retaking all general science courses to study for MCAT

What do you guys think about retaking science classes during the summer as kind of a review for the MCAT. I got an A or A- in all my basic science courses, and I'll take it with a different course code. For example, I took honors chemistry, which was Chem 2100. Now, I plan on taking regular general chemistry, which is Chem 2000. This will also help shield against potential drops in GPA from upper level science courses.
