ClassUp is best in class in tutoring! My child absolutely loves her teacher!

My 5th grade daughter struggled with her essay writing and we were too busy to tutor her. ELA tutor Robert R has helped my daughter refine her writing skills.

My son really loves the whiteboard feature in ClassUp's virtual classrooms. He can show how he solved a math problem to the tutor.

My son with me joined in a free trial, and I can feel they treated the trial lesson seriously. They contacted us before the class for my child's grade.

We're just getting going but I can see how it could help.

My son has been tutoring with Classup for the past six months. Both Math tutor Dalton Y. and ELA tutor Robert R. have been great with him. They have worked with my son with patience, understanding and compassion and his grades have improved after we started tutoring and his understanding of concepts became much better after a couple of months. Any problems in rescheduling or navigating the system were dealt with smoothly by the learning partner Jeffrey Reifman. I would recommend Classup to anyone.

The support line does a really good job. We had some difficulities with the network but the support line was really patient to help us fix the issue.
