Hello! SUMaC 2024 results are set to be released in a couple days and I would love to hear how people fancy their chances at getting in!
Please share your stats and how you found the exam and application result (if released). If anyone has attended in past years please share your experience and how you got in!
Hey, I am an international student in year 12.
I spent almost all the allotted application time (2 months) on the admissions exam with very solid proofs for every question.
I created my paper on latex and it was just over 30 pages long. Other than my admissions exam my application was not too strong.
A level: predicted all A’s (A* not given to anyone until year 13), further math, math physics cs.
Gcse: all A* and 2 A’s
Eca’s:
AMC 12 B country rank 1
Ukmt gold in intermediate senior and highest score in school history for mclaurin Olympiad.
Selected for ismtf international math competition (1 of 9)
Math tutor for over 4 years charging 55$ per hour
Head of schools math society (largest student society in school)
founded a charity that has donated over $100000 worth of items to children in need all over the world.
Developed app to help my autistic cousin communicate with his family using physical buttons.
Developed an intersection efficiency algorithm and simulation to optimize wait times at red lights.
Internships
School basketball team
SAT: 1480, 780 math (not included in application)
My essays were really last minute as I spent most of my time on exam and I submitted the application February 2nd 3 am my time. Around 6 hours before the deadline.
Hey I also applied and am waiting on a result. I was happy with most of my answers except q1b. I struggled to find many solutions for it. All I had was around 30 solutions which were all trivial and the others required an insane exhaustive trial which I found sketchy. was anyone able to find more?
Also with 1a was there any method to do it purely algebraically without any trials, because I think I found all solutions but had to substitute some values in, I think I brought it down to around 15 trails.
@Dreamuni123 I struggled a bit with q1 aswell but I was able to find 60+ solutions for 1b some trivially and some algebraically. I tried alot to do 1a without trails but I do not think it is possible, i had to substitute some values at some point.
Some bounding on p1a got me down to checking just 4 values of a I think (Ofc where u define the variables as 10a+b and 10b+c)

Essays: I think I synthesised my volunteering work, making a curriculum, and coaching middle schoolers pretty well. Maybe 8/10
Rec: bad…
Problem set:
not very good in problems 3,4,5
Forgot to prove a trivial base case for problem 3 for my induction (maybe it isn’t too bad)
Couldn’t find iff condition for problem 4 (some people did even though the question didn’t really ask for it)
Used circumradius for problem 5 (some people found a much smaller radius)
Application was submitted 2 minutes before deadline
I think I have 5-10% chance of getting in lol
I did an induction for q3 aswell! thought it would make me standout but seems pretty popular. Were you able to generalize q4, I managed to make an equation where you can input the coordinates for P1 and P2 to see weather the circle exists or not.
How many solutions were you able to find for 1b?
I only showed a few counterexamples for p1b
I had an equation for p4 involving some trig ratio so I proved the existence of a set of points that don’t satisfy the conditions but apparently some people were able to find a tighter bound (or better equation)
counter examples for 1b? we had to find 3 digit misleading numbers…
Oh I meant examples sry, I just stated that 161 644 works and a method to find similar pairs
ah fair enough. good luck, i think we should be getting results within an hour or so. Let me know if you get in. What program did u apply for? 1/2 resedential/online
My preference was
Good luck!
I’ll let u know if I get in
I solved without testing any numbers
interesting, so no trials at all?
How?
Basically, if u set the numbers as ab and bc. You can say that a*(bc)=c*(ab) meaning that c is either even or 5(Unit digit of the multiplication). If c is even, then a and b need to differ by 5.
Since (10a+b)/(10b+c)=a/c
You can write this in terms of c. c=(10ab)/(9*a+b)
Then substitute a=b-5 then a=b+5
After simplifying a few times, you can simplify the equation to:
c=b-1/2-9/(2*(2b-9))
In order for c to be a integer, 2b-9 has to be a factor of 9.
Basically using this thought process, you can find the numbers without testing any numbers
Decision is out - Rejected 
Did anyone else get a decision?
Rejected asw 
Same here 
Damn I was hoping to get waitlisted at least, this kinda gives me less hope for other camps lmao
BROOO i shouldve recorded the video essay
