Students receive 24/7 access to complete courses that cover the concepts being taught at school. Students can jump to any lesson to get help with a particular concept.
Each concept is taught through video-based lessons featuring some of the greatest teachers in America. These instructors have expertise in explaining "hard to grasp" concepts and bring the subject material to life.
Watch Sample LessonsAfter watching a short video lesson, students practice each concept with interactive problems.
Acellus uses special problems to identify where a student has a hole in their background knowledge that is making it hard for them to learn a particular concept. This special type of a problem is called a "Swiss Cheese Problem" because it helps us find holes in a student's understanding.
Video: Swiss Cheese ProblemsUsing the data gathered about the holes in a student’s understanding, Acellus provides custom personalized instruction to fill the gaps.

Read the stories below to see how Acellus transforms learning for students.
"The Acellus Program helped my son grow academically for the remainder of the school year. He went from failing grades to 80's and 90's because he was able to take his time doing the class work...
Most importantly I will recommend this program to others. Acellus is an amazing program and I am 100% satisfied."
– Andrea S.
"The way this program teaches and goes over the subject again if it was not understood is amazing! My son's reading comprehension was way below average. I now read the stories to him in the ninth grade Language Arts class, and there are many lessons on the one story. By the time he is done with the story, he comprehends it one hundred percent.
I want to thank you so much for making this affordable and having the most wonderful teachers! This is such an amazing program for kids that have physical disabilities, learning disabilities, or even just want to learn more at home."
– Debbie C.
"I have several students who can pass Algebra I and Geometry because of Acellus. There just isn't enough of me to go around...
I also tried using Acellus for an ADHD student who was very disruptive. It helped him so much! When working with Acellus, this student was able to focus and to accomplish something."
– Janie J.
