Horrible

This app used to be amazing and I was getting through my classes quickly while still obtaining the knowledge and skills. But they keep changing things and making it harder for students to complete classes as they want at the speed they want.

Amazing

I love this app. In the beginning, it kind of confused me how they taught but now it has helped me . 2.75 GPA with their help now I’m at a 4.0 GPA! Some of the teachers teach really slowly and act, as if I am younger than they think I am.

Worst program

I want you guys to kick me out right now because your program is the worst You guys have the worst teachers, the worst courses and most importantly the worst course of all time algebra either you guys kicked me out or I will go ahead and go bomb the company which one will it be? And you have an AI assistant as my guide what is wrong with you? I always have to do vector instruction because of how hard the questions are and I watch the same video 1000 times during my final exam and during vector instruction. it also randomly kicked me out for no reason when I’m on a course. So this is my message to y’all either you guys kick me out permanently or I will go ahead and go tell my mom to kick me out of this 1940s program which one will it be?!?!?!?!?!?!?

This is a SCAM!!!

I use this app to do my school work. The social and emotional class is just about submitting to what SOCIETY WANTS!! You aren't happy around your friends?? WELL FORCE YOURSELF TO BE!!! You do not share soneone elses opinion?? NOW YOU HAVE TO!! Not to mention the fact that it gives you questions to trick you and purposely get it wrong!!! DO NOT LET YOUR CHILD DO THIS!!! I do NOT care what anyone says. IT IS A BAD FORM OF ONLINE SHCOOL. It does NOT teach me anything except how to conform to societal standards like a robot, if you do not agree with their standards, then you're wrong!!

Changed for the worse

This program started out good but each update brings new challenges. Our frustrations started several months ago with videos replaying 3 to 4 times before letting my child continue. I spoke with Acellus who gave suggestions, which we tried but no success with the problem. Then, the program began limiting how much progress my child could make each week. We are using this program to catch up after being out of school several years due to medical reasons. We were told the program is self paced and my son could catch up the last 2 years to join his peers this coming fall. Now the program won’t let him due more than a few hours a week. I called Acellus and they said he can’t progress faster than the school year pace! This was the whole reason we chose this platform! Now, the app is glitching multiple times a day and causing nonstop frustration for both my son and I. We’re saying goodbye to Acellus and switching to a different company. It’s more money but at least we’ll get better quality for the money, do better Acellus!
