When dual enrollment (high school + college classes) is HARMFUL for admission ?

Thank you all very much! I really appreciate your replies !!!

Thank you all very much. My D is not planning to transfer these credits because most of them are received for a very narrow, specific topic in History. It was just a pet project, not something that she is planning to continue.

Those might be great to build ec and essays around

@SculptorDad Thanks! She is planning to write an essay about this activity, but I got scared that too many classes may disqualify her from her freshmen status. Thanks to colelgeconfidential, it seems to be not an issue.
