"I used to spend Sunday evenings writing lesson plans. Now it takes me ten minutes on Monday morning. The student profiles are the secret — it actually knows my students."

"We run five teachers and 80 students. The school dashboard and grade book alone justified the subscription in the first week. The IELTS mock exam builder is brilliant."
