You are singlehandedly carrying my grades

honestly this has been so helpful, i understand the concepts much better !!! i HAVE TO PASS STATS

legend!really helpful video, plz make more CIE math videos

good work man ,awesome ,I am a teacher and i went through your videos its good .

All solutions are correct but in the last question of 2nd we don't need to count no. Of E 0 and 1 differently you will get same answer if you just take one E so total will be 7 different letters now 3 Choose 3 from it, it'll certainly give same answer at last and also removes one case that's it...... I really appreciate your efforts

i cant understand from my teacher but i understand from him. thank you so much !

For the ii) in the first question he did, another way that you can think about it is the total number of arrangements minus the arrangements with the 2s together , i find it less complicated than the way he explained it :)

You look exactly like Grigori Perelman. The man who solved the Poincaré conjecture. One of the most difficult problems in modern mathematics

ngl it makes me sad to part with these vids LOL and studying maths made me kinda miss it. i appreciate u very much, thanks a bunch!! maybe i’ll come back if i end up doing A2 maths

"Don't bullshit yourself" Mr Intuitive 2020

thank you so much boards are in 2 months and this really helped

You’re a blessing sir

coolest math teacher

thanks to your worksheet and this video I was able to solve the permutations and combinations questions of today with so much ease 😭

you are just amazing

Thanks for the video I have my as in 2 days wish I had seen this sooner 😭😭

YOU ARE THE BEST!

aH daanggg FINALLY a teacherrr I LOOOOOVEE

you are an amazing teacher

God bless this man

I'm here again, who has exam on Wednesday?

Thankyouuu 😩

To your min.20 comment "imagine how many different arrangements of human ideas"... With nearly an infinity of permutations of human thought arrangements its amazing we can agree on as much as we do.

So helpful, thank you so muchhh

Thank You SOO Much for this It helps

THANK YOU MY GUYYY

Best best best channel

THANKYOUUUUUUUUUUUU SOOOOOOOOO MUCHHHHHH.....

thank Y so much bro , please do p3 in your next video

Hey man, amazing work putting together this Exam Hack series. I think you solved the last bit of the 2nd question incorrectly, as you didn't account for the selection of the E's. Keep up the great work

to make it easier.......you divide by the amount of number repeating . E.G at time 14:49 he divided by 3 factoril because 7 repeated three times..... You could also write this as (5!/1!*1!*3*)the one factorial comes from having one 3 and one 8 . 3 factorial comes from have 3 sevens hope that helps

THANK YOU SO MUCH!!!

Good luck to everyone writing stats on Wednesday😌

Thank u so much

Thanks man

Thanks so much 🙏

love you sir

i love how passioante you get midway when solving these then have to remember oh yeah wait im recording a video and get back to it

it is really useful thank you

Thank you

Hey man so my AS level math exam is on Monday,and I’m having difficulty in sketching graphs in trigonometry so do u possible have a worksheet or any website I can refer to ,thanks a ton man!

my 2nd year ends this may, But I'm jealous of the people who come here and find your A2 playlists in the future.

hello, in the last part of the steeple Chase question, why did we not multiply by 4 after, because the S can be in 4 different positions?

hello, ive been trying to do Question 7 on the worksheet, how would you do it with numbers?

you're amazing

Dk what would I have done without these.

THANK YOU MAAAAAAN

Thanks so much I love u

you are a boss

Hello I have a question..struggling with Q .10 b(ii) : In your answers you give 3 ways of doing it. The first I understand, the second for me doesn't seem to work out:(6C4)x(4C3)x2C1x2C1=240...giving the total, for me, to be 360...and not 180?. I understand your last method too, it's this middle one that is perplexing as to why it doesn't give the same answer as the others. Thanks. Really appreciate your work!!

Good luck for the ones doing it on feb :)

stats 1 tomorrow , thanks for everything wish me luck!!
