@@sphereishly all the best! no matter which one you choose to :) however if you go poly and take engineering course u will get to learn engineering math as well which is similar to h2 math (but the exams are way easier)
I seriously mean it when I say my discovery of your channel is the best thing to ever happen to me LOL, I just had my AMath and Chem Prelims this week your videos have helped so much! I struggled so hard w AMath (i was a single digit scorer…) but this time I actually understood what the questions were asking for !! Could you do a Biology video too? I’m not sure if it’ll even come out before O levels but I figured I’d at least ask for some tips 😢
WOW im so glad my videos managed to help you! thats great to hear :) for bio, i've never even taken it as a student so i have no idea but u can check out @thatbiotutor
wonjon, thanks for this, after my o levels i maybe want to try making videos like yours and help more students just like you man!!! (If my results are up to par first xD)
Absolute lifesaver and amazing videos, but a few errors that should be pointed out: For 15:58 shouldn't it be v > 0 and not v >= 0 ? because if v =0, there is a turn... And at 20:05 (a) you messed up the answer bit where you said 1875pi - (3pix^3)/25 = 625 (3pi - x^3 / 25) instead of 3pi (625 - x^3 / 25)
AH YES i thought of this alot as well wondering why when looking at this answer key. There is only a turn when the velocity changes sign, so eg, from positive to negative. it is possible that when v=0 it comes to a standstill, and then moves forward again. so as long as it doesnt change sign, it doesnt turn.
I'm pretty sure the question you put as linear law isnt rly linear law focused, it seems to focus a lot more on using log rules and I don't think you even linearise a function at all
i think you are right, looking back at it, it feels more like simultaneous equation rather than linear law. i initially thought that e^x/2 was the big X that you needed to make into linear form
i think its the most difficult out of all the questions in the Quadratic Functions topic leh (i tried to get one from every topic), esp part (c) can be quite challenging since they ask you to explain. then again difficulty is subjective
the cube root is just to illustrate what the a and b values are, because sometimes for something like 8x^3, they will think that its 8x instead of (2x)^3, forgetting to 'cube root' the 8
OHHHHH ive seen this, i was contemplating putting either this or the 2021 12m question as the final boss. both were pretty tough but i chose the latter cause i felt that one was more creative :>

axolotl is the superior species
I agree
I think not Mr axolotl, or are you really an axolotl? Perhaps one of extraterrestrial origin maybe?

aaaand im back here again...
As a 2023 O-level taker i am so proud to see my year's paper appearing so frequently it's only second to 2020 😌
@@MrTinkerDoodle 2023 was one of the most interesting amath papers by far :D it was the best mix of chalenging and easy qns
im watching this on the bus otw to the paper 😭 Thank yu for saving me
hope you have a safe journey there all the best ❤️❤️
AWESOME TIMING SIA… GONNA SAVE MY PRELIMS NEXT WEEKKK
AAAAA the timing 10/10, all the best
bro saved big asses today❤❤❤
make a guide for H2 math
great video, now do one for A level mathematics
thank u! maybee one day
@@wonjontheaxolotl Not one day we need it NOWWW
I love you bro
me too
Absolute lifesaver
Also, I have a question:
For the first question, can we leave it in 3s.f. or exact form
either should be ok!
for 3:28 jst remember SOAP! Same, Opposite, Always Positive(for the signs)
my glorious king posting has given me motivation to actually study 👑
LETS GO ALL THE BEST
oh my god, I need this kind of content
hope it helps!
hi! just wanted to check at 8:40 , the new equation shdnt it be -0.000121(t) instead of k?
@@chxiuyue AHHHH yes your right i cant believe i made that mistake 😭😭 ill fix it in the description
My goat has posted
LETS GO AXOLOTL IS BACK
MY KING
wonjon my goat 😭😭😭😭
AYYYY THANK U
Prelim lunch break
Let’s do this
In 3:50 the -6xy is suppose to be 6xy instead
NOOOO I CANT BELIEVE I MESSED THAT UP im so angry
THE GOAAAAAT
my lord and saviour 🙏
Literally gonna worship axolotls now!!!!! Thank you so muchhhh!!!!!
THANK YOU FOR THE CONSTANT SUPPORT
wonjon if wat of change is in m/h they nvr specify if you convert to m/s is there mark deduction
im sorry.... i cant really answer your question...
Just curious, do you'll allow to use Web based Desmos or Geogebra? or a TI-84 Graphics Calculator in JC or IB classes?
i think in JC there is a graphing calculator that everyone will use

I’m going to take my Amath prelims next week, PLEASE BLESS ME MATH-GENIUS AXOLOTL
YOU HAVE BEEN BLESSED!! all the best for your prelims you got this :D let me know how it goes 😍😍
i live for watching yt videos about my o level a math paper [currently crying in h2 math]
h2 math is really hard T_T ALL THE BEST THO

ALL THE BEST U GOT THIS
IM A BIT LATE BUT HAPPY TEACHERS DAY MATH AXOLOTL
OMG THANK U i totally forgot teachers day existed
@@wonjontheaxolotl thank you for being Singapore’s favourite math teacher 🙏
i may be na but axy the axolotl can save me when i see a 6 mark question
in september ❤
ALL THE BESTTTTT
WE NOT FAILING ADD MATHS WITN THIS ONE
YES AXOLOTL POWERS WILL HELP U TO PASS
wait how was the 0:25 question hard?? Im like 85% done my math tys and its probably the easier ones 😭
i think its the most difficult out of all the questions in the Quadratic Functions topic leh (i tried to get one from every topic), esp part (c) can be quite challenging since they ask you to explain. then again difficulty is subjective
I honestly wanted to cover a bunch of A/E Math TYS on youtube for fun, since I'm bored of studying prelims, but now what?
that sounds great, go ahead and feel free to cover the E Math TYS! :D i will definitely give it a watch
@@wonjontheaxolotl also can i ask why 2020 p2 is considered the hardest a math paper out of all the years? like what are the 'killer' questions?
@@Nytbytez its in the video description timestamps, 5 of them made it into the video. imagine doing all 5 in one exam 😭😭
@@wonjontheaxolotl dunno if im just out of touch but all of them look like very standard questions

no akemi senpai mention sad

my toes curled sorry
were you from a genshin discord server back in 2021, if u were i remember you teaching me math
maybe? tbh i totally forgot haha
you can drop me an email to remind me who you are! :D
@@wonjontheaxolotl we were in a call with like 7 people and the rest was just playing valorant 😭😭
saviour
14:30 small error
did you forget to divide -2
cuz the answer should be the same as the question
YEAH you are right AHHHHH i cant believe i messed that up 😭😭
could u do one for emath too?
i thought of it, but im quite happy with the current emath series already, so probably not
not me watching this when im alr in uni
time to relive your past o level trauma...
14:26 You got the final answer of tab 15 = 2-2sqr(3) instead of 2-sqr(3) lol
fixed in the description
Why must I only see this after my prelims bruh 😭
haha dont worry there's still o levels :)
For the factorising of polynomial if i forgot to cube root it will the answer be wrong 🙁
the cube root is just to illustrate what the a and b values are, because sometimes for something like 8x^3, they will think that its 8x instead of (2x)^3, forgetting to 'cube root' the 8

For the final boss don't you need to show it's a maximum?
@@yeet6328 no need since they mentioned in the question that its a maximum point already

ok but now do 2019 P2 question 9
