A good teacher can explain the most complicated things in a simple way,
whereas a bad teacher can turn simple things into complicated ones









You haven't fail to make things so much more simple
Thank you on behalf of those of su struggling because of our bad instructors😊

His voice so relaxing and calming! I mean I don't even come here for the math tutors anymore. I watch his videos when I'm feeling anxious or down. It's crazy because the one subject that I hated in high school brings me peace when its taught by this guy. Thank you for helping me out Organic Tutor guy. God bless you!

I'm not performing well in physics and maths but by the time I accidently click into your YouTube channel, I then started to understand the concept that you teach in every topics.Currently, I'm so very thankful, because I'm start improving this term just by your help

You’re a way better teacher than my professors. All I do is watch your videos, ignore my class notes and lectures, and all is good. I just need you around for 3 more years!

[IhasCupQuakeRealm]

You're literally gonna be my lecturer for all this💀💀

[ashimagupta]

At 11:19 how do we know where to put the line because in that graph a different spot might prove it to be a function. Great job at explaining by the way.
