Seeing as dual enrollment courses are above the high school level, is it possible to list an “A” in the class as a 4.5 or 5 on a high school transcript? Would it be weighted like an Honors course, with an addition of .5 points, or an AP class, with one point being added?
Yes. I did that on my sons’ transcripts.
My daughter created a dual column with both unweighted points and weighted. You can put any numbers you want on the transcript, but be aware most schools will ignore your weighting and use their own formula.
I did that, too, knowing they would use their own formula, anyway. It was important to us to make sure they understood even at a glance that they were college/weighted courses.
