Okay, here's a response suitable for a teacher preparing materials for a Class XI Commerce class, within the token limit:

"To download videos for Class XI Commerce, consider reputable educational platforms like Khan Academy, NPTEL, or Coursera (if they offer suitable introductory content freely). Check YouTube, filtering by educational channels and verifying content accuracy.

Before downloading, *always* preview the entire video to ensure it aligns with the syllabus, is age-appropriate, and factually correct. Use a reputable video downloader tool. Be mindful of copyright and fair use policies; only use videos legally. Cite your sources appropriately when using videos in presentations or as part of learning materials. Also, make sure any downloaded video is accessible to all students (consider subtitles for accessibility)."
