Description by CybrSecurity Corporation(from Google Play)
Acellus is a personalized, video-based K-12 learning program used by over one million students across every U.S. state. Whether your student is in school, homeschooling, or learning virtually, Acellus meets them exactly where they are.
Every student learns differently. Short video lessons introduce each concept, followed by practice problems that adapt to how your student is progressing — a dynamic learning experience built around the individual, not the classroom average.
Learn at Their Own Pace Students work independently through concepts, with personalized instruction that helps them truly master each one before moving on. No one gets left behind, and no one is held back.
A Complete K-12 Curriculum Acellus covers all core subjects — math, reading and language arts, science, and social studies — plus Advanced Placement (AP), Exceptional Education, Career & Technical Education, and exam preparation. With over 470 courses, students from kindergarten through 12th grade follow a full, standards-based path.
Stay in the Loop Monitor your student's progress in real time from any device. Scores, hours worked, and course progress are automatically compiled into printable reports — giving parents and teachers a clear view of how learning is going.
Always Improving Student responses are continuously analyzed and used to refine course content, so courses get more effective over time. Lessons are updated daily.
Learning That Goes Anywhere At school, at home, or on the go — Acellus picks up exactly where your student left off, on any device with an internet connection.
A Trusted Online Learning System For homeschooling families, virtual students, and schools alike, Acellus delivers personalized K-12 instruction that helps every student reach their full potential.

Great app, just wish that for the scholarship bonus, instead of doing two hours of work a day, students must average higher than a 3.8GPA to get the scholarship. Sometimes, doing two hours when you have other activities going on outside acellus is near impossible, especially when your class total time doesn't add up to two hours (not often, but it does happen) please change the way students get the scholarship.

This is a great app, easy to use. . Marcellus is a great program. Very reasonable price in exchange for the kids each watching a 1-hour video each week. The classes are great and not time-consuming. The kids and I love Marcellus! The reason for the 4 star is that we've been doing this for 4 yrs now, and I still haven't found a way to communicate with anyone from Marcellus. They will send emails addressed from "Marcellus teacher" and say contact me if you have questions. But you can't reply.

A very good online academy accredited school from k to 12 grades that offers scholarships to students and helps make it easy for kids to learn and understand school better. My kid loves acellus and feels more peaceful and confident as she learns and progresses. Thank you to the founder of this school.

Acellus is the best Schooling system I have experienced by a long shot. I can't recommend a better schooling system for children who have ADHD.

As a parent, I need to log in, so I can pay the tuition. For whatever reason, I can't log in now. If my kids lose their work because of a tech issue that causes me to not be able to pay, im going to be pissed. PLEASE FIX THIS ISSUE ASAP.

Parent/ customer support is of the lowest possible I.Q. & quality. Zero help. And there are repetitive issues. The school format is good tho
