The quick uploads are killing me! You're helping so many people and I just have to stop and say thank you😭📚❤

[zxdf]

U don't realize how many people ur helping bro.

[maxmaxwell]

Everytime I have a math and physics (including chemistry) problems I didn't understand at school, this CHANNEL is on my number 1 list to check out
Helps me out a lot 💔😭🌅
Just wanted to say thank you For the vids😍

[SykoMuffin]

this is a much easier method than what my teachers taught me. thanks so much <3

MR. Organic Chemistry Tutor, thank you for a well explained video/lecture on Systems of Quadratic Equations in Algebra/College Algebra. This topic is not difficult; however, students should remember how to solve quadratic equations.

[marekwink]

I was absolutely clueless in my math class until I started watching your videos I just wanted to say thank you😁😁😁

[alimbekmaksytov]

I'm sincerely thank you for being my best teacher since school (now im a student) ❤️.

[wolukawujulius]

Please make videos on Fourier series, you are the best maths tutor I have seen on YouTube 🙏🏻🙏🏻

[tob]

thank you bro, i’ll be ready for this on my test

[emirfurkankaya]

I was so ready to hear you start with "In this video, we're gonna talk about..."

[manwhathefckamidoing]

Can I use the quadratic formula instead of factoring?

[lion]

I am early hehe
And I just wanna thank you for your previous videos
I had no motivation to learn for my upcoming exam but watching your videos I am like okay it's not that bad and am trying
So thank you so much for your videos and your existence too hehe
I love your voice too ❤

[oliver]

i would love a video on conformations of acyclic compounds in organic chemistry!

[Zupdood]

"So, to solve this, we're going to set each side to 0 using the 0 (??) property."
What did you say here? I'd like to understand what rule we used here.

[dayz]

Your videos always help me. Thank you!!!

[yumbeeustace-yfbg]

I wish you new how much you are helping me
