Given your user name and mention of coops I assume your D is interested in studying some form of engineering. My experience is entirely anecdotal, however, it will give you my perspective.
My D was a Chemical Engineering student who graduated from HS with 42 credits and 5’s in AP Calc B/C, Chemistry and both sections of Physics C along with a number of other courses that took care of most of her general education requirements. She was able to use those to move on to Calc 3, she skipped the general physics courses and only had to take Chemistry 2. She knew going into college she wanted to coop. As it was she did a 5 term coop and finished in 5 years. Her 42 credit hours did not shorten her actual time in courses (she had 8 academic semesters) but it did allow her to take fewer credit hours each semester than many of her engineering peers which helped make her experience somewhat less intense. She averaged 14-16 credit hours and in at least 5 semesters 2 of those hours were playing in the orchestra. The coop payed very well. She worked a total of 22 months and made the equivalent of a good annual engineering starting salary during that period. Being frugal it allowed her to pay for around two years of tuition at an OOS public university. She possibly could have shaved a semester off of her college experience but it would have required her final two semesters being much more stressful.
Fast forward to today. She graduated this past May in the top 10 percent of her class in her major, has had a job lined up since September with a company other than who she cooped with (making a higher than average salary for a Chem E graduate) and was able to graduate without any debt. Some of this I attribute to the education she received in HS and the credits she had going into college because it allowed her to focus on fewer courses each semester. I feel the coop was extremely valuable to her. In addition to her earnings, when she interviewed they asked her little about her education but a lot of questions about her work experience.
There are many ways to reach a goal. This route worked for my D. Good luck to you.
