# Victor Loh's Messageboard

Everyone else is doing it :D

A few facts about myself: I'm 13 and I love Maths! I study in a school called Raffles Institution. Also, I'm a moderator on Brilliant for a few topics such as Algebra and Number Theory (I don't know whether I'm supposed to reveal this :D)

I'll leave more details to the comments. Have fun! :D

(I hope this works out just like all the rest of the messageboards, which have had great responses (probably because they have loads of followers like Finn Hulse and I only have 350+))

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

And what is raffle institution, is it a big school organization? because most brilliant people from Singapore are in it.Can you explain this?

- 6 years, 10 months ago

Its about midnight now in Singapore, I'll explain tomorrow :D

- 6 years, 10 months ago

ok got it

Hello :D

In Primary $6$ (equivalent to Year $6$), every student in Singapore has to take an examination known as the PSLE (Primary School Leaving Examination). Subjects such as English, Chinese, Math and Science are covered. The T-score of each student is computed (it's quite complicated because it's the relative score of each student to one another and not simply the sum of all the test scores). In this case, Raffles Institution (and a few other independent schools) are regarded as the 'top-tier' secondary schools out there (Year $7-12$) and usually you have to get $\geq 260$ to gain entry. The top scorer in Singapore (I think) achieved a score of $275$. I got $268$ :)

That's why in the Singapore Maths Olympiad, the top $30$ usually consists of students from RI :)

Thanks for the information, what are you tested one, i mean since you are in grade 6? @Victor Loh

- 6 years, 10 months ago

- 6 years, 10 months ago

Sorry you didn't get my question, i mean what do you get tested on 6 grade?

- 6 years, 10 months ago

I sense RI will not be No.1 in SMOJ for obvious reasons :D

- 6 years, 10 months ago

Why?

- 6 years, 10 months ago

I would think Joel Tan would be 1st though.

- 6 years, 10 months ago

He got $1$ question wrong in $2$nd round

- 6 years, 10 months ago

Question 5 what did he misread as?

- 6 years, 10 months ago

Idk

- 6 years, 10 months ago

I too got 268 (((:

So what do moderators actually do out there ?

- 6 years, 10 months ago

We help to edit problems for clarity and promote posts to improve the experience for everyone :D

- 6 years, 10 months ago

Wow! That's news to me. How did you become a moderator??

Hello Victor XD How's life XD

- 6 years, 10 months ago

Hi Charlton. Could you tell me how all you Raflles' people are uniformly so good at math?

- 6 years, 10 months ago

@Charlton Teo What is raffles institution?

- 6 years, 10 months ago

It's a school :D Refer to my other comment.

- 6 years, 10 months ago

Are you sure you are 13? ^^

- 6 years, 10 months ago

Fine 12.5 :/

- 6 years, 10 months ago

EDIT: I just realised I was being blind.

- 6 years, 10 months ago

Dude, you're the same age as me. :D

- 6 years, 10 months ago

- 6 years, 8 months ago

- 6 years, 7 months ago

I think you're a few days older than me (I saw it in some other comment but I forgot) but anyway when's your birthday?

- 6 years, 10 months ago

Dec 5, yours?

- 6 years, 10 months ago

- 6 years, 10 months ago

- 6 years, 10 months ago

Youth is beast. :D XD O_o (Emoticon spam) :) <:~)

- 6 years, 10 months ago

15 may

- 6 years, 8 months ago

In your profile it is 14.

- 6 years, 6 months ago

It's not really people in Raffles become good in math, its mainly because people good in math come to Raffles XD

- 6 years, 10 months ago

Lol ok :D

- 6 years, 10 months ago

I hope the following comment doesn't become controversial.

YES! I have seen that Brilliant has a lot, almost half of the members from India and SINGAPORE. So, yes, USA, this time, it's Asia winning the race for the love of MATHS.

But yes I think that Brilliant doesn't have a moderator from India. Is there any??

- 6 years, 10 months ago

It's not hard to guess one.

- 6 years, 10 months ago

Really? Who's he/they? I have some names in my mind who can be...

BTW, celebration time for you!!!!

- 6 years, 10 months ago

Why celebation and who's the one from Inde? And BTW-Kartik are you good at french? DO you have it as second language in school?

- 6 years, 10 months ago

Celebration because as you might also be knowing that Djokovic recently defeated Federer in a very exciting match at Wimbledon and Nishant has Djokovic in his profile pic, and so, he must be in joy celebrating his 'icon's' 7th grand slam win.

News apart, ah I liked that Inde[french for India(for those couldn't understand)]. Yes, I have it as a 3rd language in my school but i don't know if I am good at it because the real challenge comes only when talking to a real french guy..

Maintenant, tu sais 4 langues - l'Hindi(je pense), l'anglais, le francais, et Tamil....!!!!!!!

- 6 years, 10 months ago

Well I actually watched the whole match. The thrills were clearly visible in the 4th set when FedEx clawed back from a break down to clinch it 7-5. Congrats to Djoker. And about my avatar, I only admire his game. As such I don't support any individual. Do you follow tennis everytime ? How about you @Victor Loh ?

- 6 years, 10 months ago

Yes, I do, actually, I follow almost every single sport. But still, I follow tennis, cricket, and football the most and I love to watch the matches. Well, I was a little disappointed in the finals match because I wanted the CLASS to win and after the 4th set, I was very confident about that even but still, I am happy for Djoker and he deserved it. Cheers!!!!

Back to studies(although fully after the WC) and I really want some help especially in Geometry, E&M, and Calculus. being my elder, please advice me something!!!!

- 6 years, 10 months ago

I don't think it's the right place to talk about in detail Kartik. For Electricity and Magnetism I'd suggest go for H.C.Verma for concepts and once you done with that get onto I.E.Irodov . BTW which standard are you in now ?

- 6 years, 10 months ago

H.C. Verma and IE Irodov, yeah, I have them(one PDF and other book) but don't have much strength to study them regularly, being a 10th grader. BTW, can you suggest me something for Geometry and I hope @Victor Loh also comes in this conversation.

- 6 years, 10 months ago

My geometry isn't that good

- 6 years, 10 months ago

:(

- 6 years, 10 months ago

Why(How) did you drop a level in Algebra ?

- 6 years, 10 months ago

Sharky Kesa? I don't know for sure.

- 6 years, 10 months ago

No, I was going to be but mum declined.

- 6 years, 9 months ago

Hi Victor! Sorry about the false claim on Calvin Lin's Messageboard but I really wanted somehow to get the criterion(a) for becoming a moderator so could you fill me in?

- 6 years, 8 months ago
