  1. @Fred Lee
    I am so glad that you like Galen’s teaching video.

    As you say it is helpful website for middle school students.
    So it is great that if you could share Liveism.com to students in need.

    Thanks.

  2. The proof and explanation of geometry from free video is very clear for me.

    The teacher should be a great math teacher. If you are a middle school student, you should use the excellent website to study or review it.

    Thanks.
