Am I Overreacting?

So, I have a question. I need to know if maybe I’m overreacting.

My 5yr old is in homeschool. At first it was good, I did have a few concerns about how many things they had to do, but now, ITS WORSE IMO. It’s a normal schedule, 8AM-2:30PM (you can even work on things afterwards, aslong as it’s done before 11:59PM)

At first she had 3 live classes, and 4 lessons; each day M-F. No live classes happen on Friday’s though. She recently got a new teacher (she started this Monday) and now she has 4 lives classes back to back from 8:45AM to 2PM. This wouldn’t be a big deal, but she has 5 lessons, and each lesson takes about 30 minutes or more to complete.

The lives class time are:
8:45AM-9:30AM
9:45AM-10:15AM
10:15AM-10:45AM
1:30PM-2:00PM

And keep in mind there’s 5 lessons that range from 30 minutes EACH or more.

I don’t know if I’m wrong for this, but I feel like this is too much. Way too much time for a 5yr old to be sitting infront of a computer. And if I space it out accordingly she’ll be doing school work ALL DAY.

And if I am overreacting and this isn’t a lot, how can I manage the time where she gets done before 3PM and still has time for her breaks during the school hours.

I am struggling to figure this out.
