Dear Sal, I hope this message gets to you. I started watching your videos in grade 8. You're gentle and emphatic approach to teaching(and that soothing voice) was the only instrument that could get the wonky and sometimes dizzing concept physics chemistry and math through my thick skull. And today, after six years of being taught by you, i am filled with a feeling of immense gratitude for all that you've done. We may never meet(or we may) i just want to say thank you, for being a great teacher and a great inspiration
How can we help?
