"Just had to write you a quick note. I'm currently recording grades for Physics 101 and I have to tell you that we had such fun with this program. The labs were great and exciting and most were even practical. Building motors, starting fires, building batteries - all very cool stuff. Great job again with the videos. We feel like we learned a ton and none of it was all that painful. Thank you for putting this all together so prayerfully. Thanks for giving God glory with your work!"
