Homeschooling: good or bad?

Current Events

My gf home-schooled her kids for a year, after disruptions/issues from Covid and moving around (her husband was in the Coast Guard) left them behind or not receiving credit in certain areas. Seemed to work out well for them getting caught back up or even exceling past where they needed to be. Of course, once they were settled back in and she went to work full-time, they went back to public school and are still doing well.
