User reviews

This is dumb

I do school work on here, it sucks because one there’s no deadlines, I can do it whenever so I’m super behind— and two in English writing assignments it label words in other languages as wrong. At this point I’m ready to submit one FULLY not in English because there’s no reason I should have to remove the last name of someone’s name when giving credit to them in my work just cause it’s not English

This school is great

In my opinion it’s not better than private school but I like it I’m doing it right now it’s a pretty good school but I wish I could raise it to where I was before I joined the school

Hey

Glitched and slow

New step limit is irritating

I’ve been using this program for the past 6 years, and I’ve loved it until the recent updates. Before, I believe the 40 steps per week limit was okay, it was enough to get stuff done. Now, I can barely get percentages up for my classes (even if I’m behind on classes) and cannot graduate early like I was looking forward to. If the 40 steps limit comes back, I’d recommend this program to others.

False advertising

When I first started Acellus, their main thing was self-pace, and now it's not. I can only do a couple of steps a week, and it's holding me back from returning to school on time. If I had known this from the beginning, I would have never done it. You all are so inconsiderate, selfish, and liars, and you will end up losing customers with your false advertising. Even when my mom tried to call, your employees sounded like they don't care. Keep this up, and you will lose a lot of people. I regret picking Acellus; they changed.
