So I'm here studying for Stats 1 now, yesterday I wrote P1 and all I used was your hacks 🤣one even came in the paper, the questions you had in your worksheet 💯your work is appreciated man. My mother couldn't afford a tutor to help me in maths, I'm so glad I found your page, my mathematical understanding has enhanced because of you and I find myself loving math more and more now, you're a blessing. I know for a fact I'm getting an A in my finals in October and that'll all be because of YOU. I pray your youtube channel grows more and more and that all good things come your way, thank you again for helping me out.
Amazing I'm extremely happy for you. Good luck with Statistics and your finals. Feel free to ask any questions here or via email :)
@@Intuitive_education That'll be great! Could I please get your email?
@@esethudlamini6374 everythingsintuitive@gmail.com. I am going to be setting up some free one on one sessions for people over the next month. So if you are interested in that email me.
you know you're a professional exam hacker when you film your youtube videos inside a tent.
Haha man's out here grinding for the people.
Please tell me what you guys think of this. Are these exam hack videos helpful? What could be improved upon? I make them for you so any feedback would be great.
Intuitive absolutely amazing
Intuitive man GOD BLESS YOU brother ... you are saving me from getting bad grades brother .... it’s really HELPFUL ...
SOOOO HELPFUL. You taught me more in these videos than my teacher did in two years!
very helpful bro!
Please make the videos a bit longer (explain more questions) and if possible make videos for hard questions along with explanations.
You're amazing, glad I found this eventhough my exams are closeby
Great work keep it up 👍👍
Did your p1 worksheets(all of 'em)
Did your physics work sheet (only my weak topics)
I was laughing at the paper
Expecting a good grade (A)
"The more we come to know;
The more we will realise we know nothing".
Who would've thought that i would ace my exam watching intuitive.
There are such legendary youtubers sitting on a tent,
Hacking the CIE exams and changing viewers whole carrier.
Man you are really a LEGEND .
I'm just out of words to say,
just keep up your work ,
it helps a lot of us who watch latest episodes of one piece a day before exam😅.
We're so happy we saw a legend doing calculus without a calculator.
one of the most underrated channel on CZcams
I hope you grow exponentially!!
I'd say ;)
thanks to your videos i got a 95 in maths......may the Lord bless you
Yoo, thats illegal man, you can't be hacking exams like that.
Don't tell the police.
Watching your videos seem very illegal to me. How the hell are you so amazing?. No one on earth would make these videos without getting paid. I swear, I hope you grow drastically. I already informed my friends about your channel and they feel blessed. You are a legend. I will never forget you. Thanks once again.

Thanks dude
I have a Binomial, Geometric and Normal Distribution exam tomorrow online (I'm in quarantine but tested negative). Just binge watched your videos! Already found you some months ago and your channel is just exactly what many students are searching for! I have already shared some videos to friends. The worksheets are also game changers!
Thank you so much! I have been struggling with standardizing for 2 weeks now and finally, I understand it yay.
amazing work, thank you so much! just shared to my friends! i hope your channel continues to grow!!
one of the best channels I ever went through, not going to lie, it helps a lot in math especially in this era of online school.
They are great, honestly. I've seen a drastic improvement in my work. Thanks to your worksheet, it's easier to understand just by taking a glimpse of the question what the examiners want us to do. Couldn't be more thankful :))
Really appreciate you taking the time to write feedback. Thank you :)
this whole series is AMAZING, for the first time in my life i can say that probability and statistics isn’t confusing! thank you so much
thank you so much for providing this content for free. you have no idea how many people are becoming better at math because of you and whatever they acheive with this information in life later is all credited to you. this is social service at a whole diff level.
Mans out here filming and grinding from a tent, sheesh. Honestly so grateful, for real. You, your videos, AND THE WORKSHEETS legit saved my grades
so you made a years worth syllabus so easy that i only need to prep for 3 days ? damn i guess ily
Can’t thank you enough for these videos.😭😭😭😭😭❤️❤️❤️❤️❤️
This video literally giving me tears.
Thank you.
Your videos have been really helpful to me. You are a legend, Thank you so much!
Your teaching style is amayyyyzingggg !!!!
Just want to let you know that these series have been so useful for me whilst studying for my exams. I've been watching both the Stats and Pure ones and it's definitely helped a lot ! so thank you very much :)
Great explanation! Thanks for the videos
Keep it up dude, you are great...
Shot bro, if it wasnt for you, i would still be revising the first topic. Because of you I can cross out every topic and understand better. Hope you have a good life becuase you are a life savier
Great work!!....thankyou so much
Such a life saver
Exam tomorrow at 8am. If I pass, its all thanks to this channel. This dude be my hero
Did you pass?

You're a lifesaver
amazing bought the patreon after watching 3 vids
Thank you soo much for this💙
This vid really helped me alot💫
Absolute lifesaver, can't express in words how thankful I am
then express it by money ok😌?
@@annaelizabeth6195 I'm actually planning to pay for his patreon next year for A levels ¯\_(ツ)_/¯
For now, I'll help by adding to his view count ig
@@boxbird5723 Bruh...I was joking haha Best wishes for you A levels 🙃
dude ur an actual fucking legend no cap 😫❤️
THANKYOU SO MUCHH
Thank you, this series is going really well.
Glad you find it helpful :)
no words man.....just great just.......so good.......idk man just hats off to u 🫡🫡🫡
i have happy tears in my eyes
This is such good practice! Thank you for the worksheet! I just found a small correction. In question 18 ii) you forgot to multiply the probability by 52 to find the number of days.
Thank you so much Sir
Dude. Thank you. Please make more
There’s no more to make for S1 I have done every possible question for for exam
At this point I do not know if I should cry tears of joy, or sadness. Happy because I am finally understanding all this, but sad because I literally stumbled upon your channel a few hours before my paper! :( I'm still glad I did though, and bless you mister for your good work. 1. You earned yourself a loyal subscriber and 2. I'm gonna share your channel with my juniors so they can benefit from it. Bless you!
I understand your pain I have my Stats paper tomorrow 😔....How did your paper go?
Really helpful.
Glad to hear!
no homo, fucking love this guy man
can i ask why is your S.D not rooted here but in parts 2 and 3 it is?
Sir your teaching is just so awesome but i think u had did a minir mistake writing 0.835 instead of 0.538
hey man, could you explain me why does it go from P(z « -0.538) to P(z » 0.835)
it was an accident
One thing I've noticed in youtube tutors is their effectiveness in discussion decreases with time but you always made sure every video was upto standard that itself surprises me and the fact that you put all this work in to finalise the worksheets yet sharing them for free makes you that one teacher I'd never forget. Mr... you made me realise that you really don't want a teacher to physically be present to really respect and bond. Each and every video I watch adds upto how much of a great person you are and the level of respect and gratitude just keeps adding up.THANK YOU SO MUCH (this is the least i could say) I'm gonna be like you one day
Uh could you pls explain why you took the value of t on the left? Why not on the right as its 90%?
hey i have a question. at 9:25 why did you pick the value for 1.2 in the table? also, i appreciate you so much youre out here saving thousands :))
He's kinda doing the opposite of what he did earlier. So instead of first having the z value and using the table to find the corresponding probability, he's figuring out which z value (or combination of values) adds up to 0.9 (the probability)... It sounds hard at first, but a tip is to look at the closest number to the one you're searching for in the table, and it'll be the one before that. The table is also in ascending order, so that makes it a little easier too. Hope this helped, and good luck with your exams :)
welp i have my exam tommorow afternoon and just discovered this, should i pull an all nighter ?
LOL same bruv, ill pull an all nighter aswell bc its a pm paper
Haha all nighter here too lmaoo
@@H.M.Dar. ganngggg
yes
Same
PLEASE DO GEOMETRIC BEFORE WE WRITE OCT/NOV
in que 8 ii) in the last step you wrote P(X< -0.625) but instead it should be P(X> -0.=625)
for question 9 part (ii) how did you know how to draw your first graph? like how comes t couldnt be on the positive side? and also question 10 (ii) the graph part is reallly confusing...
Because the P(X>t) = 0.9 so t must be on the left side of the graph as half of the graph is 0.5. If it was P(X
When X > t, it means X will be on the right side of t, and when Xt is 0.9, which means the "area covered by X" per se is 90% of the graph. So if 90% of the graph is on the right side of t, t has to be on the left (negative) side of the graph. Hope this helped :)
I already sat for my Pure 1 paper and it really didn't go that well the paper was hard but never i did my best i hope its not the same case with Stats tomorrow
In the first question on your worksheet, why is the standard deviation squared in order to find the z value?
The standard deviation squared is the variance. In statistics we use variance as it is always positive (due to it being squared). In every question I will use the variance to make calculations.
@@Intuitive_education but X~N(mean, standard deviation) so is there a need to square root 3.6 if it's already the standard deviation and not the variance?
@@jabulanicharamba6273 no its deffo X~N(mean, variance) haha :)
I just had a question how did you get 0.835 instead of 0.538
He used the value of 0.538 only he made a mistake in writing it
@@nathandias6013 yep thanks realized that after i went on to do the worksheet
I was losing my mind fr
i think it supposed not to be 0.835
Yeah how did he get 0.835
to help you out he might have made a mistake because if you check the same question he did on the worksheet provided in the description he doesn't use 0.835 instead he uses 0.358
@@natio8497 it's just a mistake he made while speaking, he used the value for 0.538
13:38 is it 0.538 or 0.835 ?
Please tell me how you solved question 4, in it you wrote (P(Z
Surely you're smart enough to see that is just a little mistake I must have just wrote the numbers wrong. P.s Chillll man damn
@@Intuitive_education dude, i am in a bad situation, i got my s1 on 14 october, i need to prepare this asap, your videos have helped me alot thanks for your efforts... about being chill, i can not chill, dont have time for it
question 4 (i) in the workshet you bymistakenly put 2.535 in the workings instead of 2.353
when will you start doing hack series for Pure 3?
When is your P3 exam?
@@Intuitive_education Oct/Nov
so when will you start doing it?
@@abdelrahmanyasser7363 I don't know. I really will just do an exam if a lot of people want it. But I am not sure what I will do after S1.
yo bro do you teach how to use calculators?
Last part of question is p(z>0.538)
Why don’t you use compliment property of probably to get phi(Z
How do you know when it is a standard deviation or a variance?
From what I've seen in his worksheet and more past papers, the question usually tells you
if it's written in the form X~N(x , y), then the x is always the mean and the y is always the variance, so you would have to square root the y. However most of the time its worded and they just say "the standard deviation is ....", or "the variance is ...."
I see now, thanks. Just a tad 6 month latr haha.
How did it go from 0.538 to 0.835??? 13:50
Heyy...In the worksheet, question 1, why is the standard deviation square rooted? while finding the z value???
Whenever its written in the form X~N(x , y), the x is the mean and the y is the variance. So he hasn't square rooted the standard deviation, he has square rooted the variance in order to find the standard deviation. :)
tysm@@puddleduck1405
i lost my head on where you got 0.835 in the end to realize after 20 min it was a writing mistake 😭
Im sorry, may someone please explain how we got 0.835 at 13:40? Thank you!
he meant to write 0.538 and wrote 0.835 by mistake i think
Hey I don't understand why did u put -1.281 instead of 1.281 how was it asymmetric?
Since the mean is in the exact middle of the curve, the Z's on either side are equal, just the ones on the left are negative values
The worksheet documents do not match the one on the video
Yeah they are my written answers!
13:40 I think there is mistake, it is .538
you are hero a sir. pls i want to know if it is only maths
I'm afraid that sentence makes zero sense.
Do you have worksheets?
All worksheets are in the description box under the video. Click on the link to download them.
Can anyone please tell me why he used 0.835
It's a mistake
ohh thankyou @@scrollrester
yo why is question 16 (i) Z = --1.751
you teach good but is that a tent?
Yetp
We out here
Excuse , there was one place which went wrong I thought . About 14min the z should less than 0.538 but you wrote 0.835. May be that's my own wrong😊
He low-key sounds like Jon snow
Where is he recording in 😂
ok im kinda attracted to u man ❤
am i tripping or are you in a tent
I can’t seee ur face is in the wY
?
@@Intuitive_education LOL I said ur Face Is in the way I can’t see
