Should I retake lab part of lecture course if already retaken lecture?

Two years ago, I went to several medical school fairs and conferences, including the last OPM conference, and asked about retaking the prequisities for medical school. All of my most recent pre-requisites for medical school were taken about 10-12 years ago. But because they are “expired”, I was advised to retake some of them again, so I am doing so. I am wondering about laboratory classes. At my current school, they separate the chemistry laboratory classes from the chemistry courses, for 2 chemistry and 2 organic chemistry courses, there are two combined labs, not four. Unfortunately, these courses are costly, and their meeting dates are inconvenient for me.

I wonder if I can just skip these, as I have already taken the labs, and isn’t it the lecture content that is most appropriate for medical school? I earned mostly A’s in these courses years ago, and I am earning A’s once again.
