Actually @happy1 it does but you can be rude if you would like to. I’m pretty sure Texas Tech and SFA etc. don’t give a crap how many classes I’m in during senior year. If the admissions counselors won’t answer I have to ask someone. This is a completely different situation.
I also haven’t hit send on any other applications because I can change on the common app if I drop the class before applying so I don’t have to inform them. It won’t matter for them because they will have no way to know why the class was only one semester.
