Here’s what consumers have asked with answers from Connections Academy staff and previous consumers.
I have had a daughter switch from connections to bricks and mortar. As long as you are not switching mid semester, there shouldn't be a problem. In Indiana it is the same as switching any other public school. My daughter switched back to connections and had no problems then either.
There are 2 semesters each year. So, if you were to finish semester 1 3 months early, you could get a head-start on semester 2. However, I'm not sure if they allow students to go onto the next grade, and if they did, the student would have to take an exam to prove mastery in whatever courses they are skipping.
