One day we really got to get together and just sort Kevin out. Mans helped us through everything - through last minute studying - through almost leaving the subject. Mans always got us. 💪💪🙏🙏
I improved by 23 percent thanks to you sir im very grateful 😊🥰
I got a distinction on both maths and physical sciences all thanks to you May god bless you
Your videos are really helpful I always pass my test with distinctions 🙏🏻🔥❤️🏆

Awesome Gomolemo, well done and keep giving your best :)
give Kevin his flowers he deserves them ! thank you so much sir i fully understand chemistry now!
Hi! Your videos are so useful, I'm forever grateful. Please make videos for redox reactions & acids and bases grade 11 🙏🏾
Mate, you saved me… THANK YOU SO MUCH! btw you’re better in teaching than a IGCSE teacher hehe

Kevin knows what he's doing Thank you for taking your time and helping us
You are the best physics and chemistry teacher ever
Thank you so much. This has helped me alot also because I'm writing my chemistry test tomorrow. Really appreciate this man, thanks alot🙏🏾
YOURE VIDEOS SAVE MY LIFE! THANK YOU FOREVER GRATEFUL
You're the best Kev, you've been really helpful on this
You are a life saver. much appreciated
Bruhh i like thevway he talk 😅 So interesting to listen and me who is smirking while watching 😢

Muhammad, they have multiple ways of asking this in tests and exams. They can give you actual yield or theoretical. You must just make sure you fully understand what it all means and then you should be good to go :)
Thanks man i never understood this until i watched this video
wow you do know how to kill fear and insecurity huh? I feel secured now I totally understand and it all because you,thank you sir Kevin✨🌹❤️😭🥰🥰🥰🥰

Thank you sir❤ 🙏
at 5:25, should the molar mass of 2H2O not be 36? instead of 18
Thanks again ❤
Thank you so much
Thank you❤
Kelvin, in physics when they ask you to calculate theoretical acceleration, do i still use the same formula
Kevin you are my GOAT🐐
another day another physics topic i struggle to understand😅😅
GOD BLESS KEVIN SMITH
Keep up the good work man you saved me 🔥🦍🐐
May God bless you
Salute 😭🔥
thats a very good analogy right there 5:58🤣
Thank you Kev 😝😜
Will it always be 1:2 ratio?
With the last isn't the 40g for 70% arcute? So why are we using it for the 100% arcute?
I have an exam tomorrow and i think it is gonna be a piece of cake,btw ur funny
A mixture contains 78% apatite (Ca 3 (PO4) 2 .CaF 2 ). The rest of the mixture does not contain any phosphorus. Calculate the content (mass percentage) of phosphorus in this mixture. How do I do this question?
wow thanks 😊😊😊

Neo, I hope that did not happen to you. If it did, then you should take the next few weeks and holidays and put in a few hours of studying every day. Never ever give up and always continue to push yourself to your highest level.

@@kevinmathscience thank you so much needed that 🔥✊ Your channel has helped me so much
sir could you please consider including steps in your videos i notice that it is easier to learn with a set of rules
Mr Kevin, please make videos for redox reactions, grade 11
What if you're givin the percentage
Is this not similar to the empirical formula
Senku(from Dr Stone)
bruh i should be thanking you 😭
Where did you get 90?
I want you to help me with a question Kevin by sending a photo but I can't.

Hello :) Please note I only answer questions relating to the videos on my youtube channel or to my online course. Due to time constraints, I cannot go beyond that.
I have problems with Acid and bases can you pls help😓😓. This video was very helpful🤭🤭☺️☺️.
Sir please slow down 💀
