the 33240 is meant to be 32400 by the way in part c

in question 2 why are u not subbing in 0 for y1 and x2.??????????

the formula and tables doesnt have part (ii)? and for part (c)(i) it says that A is the initial amount of caffeine consumed, so you cant say that A then = 32mg because thats not how much caffeine was consumed initially

part (b) is incorrect as V(t) is the initial function that we were given, it's not the derivative which is V'(t), and the question is phrased in such a way where it's impossible to try to justify that "it's assumed" that we are asked to sub in values into the derivative similarly in (c)(ii) we are asked of a feature of the graph of V(t), not the derivative V'(t), so it is not appropriate to say that we can use information from the derivative to answer this

❤❤❤

how do you get the t values for the graph in question d

can you elaborate on the very first question?

I think you forgot to multiply the 9/64 times the 18x squared

Jesus thank you so much

Thanks for this. Also made me feel a lot less stressed about the whole thing so i appreciate it !

Cheers

Awesomesauce!

Nooooo, I've already missed 5 days :( I'm sorry I failed the challenge. I'm doomed. It's over. Pray for me.

For part c the last figure should be 81/4x3 (cubed instead of squared) I think

Hello Eoghan, thanks for your clarity! On part (a), can I ask - would dividing 1 by 22 and getting 0.045 count under 'or otherwise', as you would to convert any fraction to decimal ? Seán

Great 👍🏻 Stay comnected

Hi, I was wondering what topics are being covered in the revision class on Saturday?

Do you know what mandatory experiments come up in section B? I have learned Tests for anions Flame tests Chlorine in swimming pool I might leave out the rates of reaction chapter because I don’t want to learn any more experiments. Do I need to know the gas experiment or the heat of neutralisation expt or anything?

Physics predictions?

thanks very much, John! I have a question - when is the last chance to pay for your 3 hour course this Saturday? I think there will be a deadline for the payment

They confirmed recently that the option question will appear as a fourth part to Q11 !

Very Nice Video Go A Head

Mup

thank youu <33

thank you for this :)

Hi Could you do one for economics aswell? Tks

hi could you do one for economics? Tks

you're really cool!!!! thank you so much <3

theres so many proofs but not one came up last year

Much appreciated.

Hello everyone. A lot of people are asking if Financial Maths could come up in P2. While it could come up as the context of a question it is highly unlikely that it would come up as a question where you have to do the skills associated with a P1 Financial Maths Q. So there could be a question about a company making money, or homeowners paying their mortgage but the skills tested would likely be stats and probability skills. Overall, I wouldn’t speand time and energy revising financial maths over the weekend. I hope that helps!

very helpful, thanks

for paper 2 could you link the word document in a link with the video please :)

Hi, I have one math question about related rates: A snowball metls so that its surface area decreases at a rate of 0.5cm^2/min. Find the rate at which the radius decreases when the radius is 4cm. (SA=4pi r^2).

Any chance of something like this for economics? Please

Inspirational stuff right here lad. Different class.

You’re a legend 🙌

Note: In part C of the question: The lenght |PR| should be 6.3 not 5.3. It won't affect the question for the vast majority of students, but the correct length is 6.3

Nice👍

Where's question 5?

I know for question 9 c how did u know to use geometry series
