Not a college student here, just a senior citizen doing some good exercises for the mind. Good depiction, good narration, very good product. Thank you for putting this up on YouTube

[NomaMPride]

You deserve my school fees because you literally teach me everything.

[hibbs]

Well boys, it was one hell of a journey. But, after this month I will officially never be taking a math class ever again. It was one painful ride.

[honorrobertson]

Not all heroes wear capes. This man has saved everyone's grades

[Mmichel]

Everyone should tip this guy $5. He deserves it. If you watch his videos leave similar comments and spread the word. I would be getting through engineering without his tutoring.

[raymondkyruana]

Just want to let you know that you and a couple other guys on Youtube greatly helped me get through my Electrical Engineering degree (and Biomedical minor)!!! I want to seriously thank you from the bottom of my heart for making these videos and helping teach these topics better than professors who are paid 6 figure salaries. I wish you taught every course haha but man you do a lot! Thanks again for everything... It will be kind of sad to not have to watch these videos anymore but who knows, I might need them in the future! I hope the education system changes soon

[cherryclorox]

Crazy how you carried my all through high school and now I’m in college still watching

[Benedict_Miriti]

You literally my best Youtube math tutor that i've ever met.Keep uploading more math videos you saving most of us.Big

[smellymewi]

You made a confusing topic much more simpler and easier to understand. The prof at my uni just rushed through and still joked that if we don't understand, its all right to fail. like wtf lmaooo

[derrickcastillo]

youre way better than any math teacher ive ever had thank you so much for all of your hard work you got me through cal 2 and are helping me get through cal 3

[majdlabbad]

dude really just taught me my lecture in 15 minutes and it actually makes sense lmfao, I owe this man so much

[esiportia]

Daddy please i really like your tutorials, i wish you were in my field in civil engineering
You are my number one choice when i come to youtube

[vijayalakshmisureshkannan]

Due to lock down it was really tough to get a tuition, I understood nothing from online class, this helps me a lot .Thank u very much

[jingyiwang]

I am really grateful for this video! You have saved me when I am previewing for my linear algebra class next semester.

[samaabdelgelil]

You are so good at explaining things simply and easily ..Thank you for your help.

[txtugoe]

At this point this is still relevant, probably the most influential way to teach a student, he has some good way of teaching articulate and understand that as individuals each of students has different backgrounds, again thank you for saving my grades. My physics exams, my calculus I II III all has straight As because of you, i can't thank you more than enough for everything.

[georgesadler]

Professor Organic Chemistry Tutor, thank you for another classic video selection and awesome explanation of the Cross Product of Two Vectors in Calculus Three. Cross Product is also introduced in Engineering Physics One, Statics and Dynamics. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

[efoglio]

Man I used you through all of my years of college, and I’m finally back to prep for the FE exam, thank you man you’ve been there the whole way

[amunajr.]

Man u r out of this world...pls dont stop posting...! U r our only hope in maths

[hadis]

Why go to school when you can just check what they teach you during the course and then just watch Youtube videos about the topic? My math lecture is starting in 2 hours and I'm already studying the topic with the help of this video. Internet is making schools feel so obsolete.
