The new update sucks

Before the update it was really good and i could actually go back and catch up on lessons i messed on the past day(s) now it wont let me- and for people that cant see or read properly because of sight problems or like me who has dyslexia i cant always read right, thats why Read Out Loud should be there always for you to have- and the AI??? Why use AI when it was fine before it?- it was way better before the update and Acellus should really go back to how they had it in like 2022

They got money hungry.

Originally I started using Acellus back in 2020. It was so convenient and I could finish a class in a month. Recently they added a feature where after a weeks worth of work you can’t work in that class until Sunday. I’m behind and now I cannot catch up. It also keeps removing steps so classes are becoming even longer. Genuinely it’s such an inconvenience and is SO frustrating. My sister has emailed about this and they completely ignored it. Change this feature Acellus!!!

This app is bad

Do not get this app if you pulled your children out of school and were behind this app will not let you catch up. It makes you feel stupid and it does not do a good job at keeping track of your schoolwork. I really hope the next program I do is much better.😠

I hate Acellus

It’s scammer scammers scaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaammmmmmmmmmmmmmmmmmmmmmmmmmmmmmmerrrrrrrrr
