We cover from counting through Algebra. We have seen students as young as 2 years of age achieve success. If you have an older student that is struggling with upper-level mathematics, it tends to be due to a misconception that occurs in Algebra or earlier. Our system will detect gaps in understanding and fill them with activities that were proven by third-party research to effectively teach the concepts. Our UI ages with students and we have graphics that are age-appropriate. We continuously create new experiences and curriculum.
