Singapore Physics League
A fast-paced team contest to solve fun physics problems

What is Physics League?
The Singapore Physics League (SPhL) is a 4-hour online competition, where teams of 3 - 5 students race
to solve fun physics problems. Learning and doing physics is a team sport - gather your group of fellow physics enthusiasts to participate as a team and discuss interesting physics together!
scheduleWhen and
where?
SPhL 2025 will be held on
5 July 2025 (Saturday), from 9:00 AM to 1:00 PM.
As the competition is fully virtual, you and your team may
be physically located at any spatial coordinates of your choice!
All you need is a computing device with a modern web browser and a stable Internet connection in order to gain access to our online platform. You must log in to view problems and submit answers.
[NEW!] Selected teams from the Senior Category will be invited to a physical event: SPhL 2025 Grand Finals, on the afternoon of 19 July 2025 (Saturday) at the Singapore University of Technology and Design. We're still working out the details. Stay tuned!
groupsWho can
participate?
This competition is open to all students currently
studying in a Singapore secondary school or pre-university
institution (or equivalent). There are two categories in the
league:
SPhL (Junior): for teams whose members are all in secondary schools
SPhL (Senior): for teams whose members are all in pre-university institutions (Junior College, Millennia Institute, [NEW!] Polytechnic, ITE, or equivalent)
You should form teams of 3, 4 or 5 students. Your team can comprise students from different schools.
How it works
settingsMechanics
At any time, your team will be given access to 4
problems. You can submit your answer for any of these
problems whenever you wish, and the website will give
instant feedback on it:
done If your answer is correct, you gain points, and you will be prompted to select a new problem to unlock.
close If your answer is incorrect, you can re-attempt the problem for partial points.
quizProblems
Problems vary greatly in difficulty level; some are
comparable to questions from your school exams, others
are closer to national olympiad questions or even
beyond. The examinable scope will follow the
IPhO syllabus. There will be some differences in the problems for each category (Junior / Senior).
For a rough sense of the style of problems, view past years' SPhL problems here.
lightbulbStrategy
You should communicate and coordinate closely with your
teammates, but there should be no communication with
anyone else during the competition (e.g. family members,
friends in other teams, etc.).
This competition is completely "open-book", so you are allowed to use any reference materials or even computational tools at your disposal. [NEW!] (with the sole exception of generative AI tools) You can even learn some physics on the fly if the problem uses unfamiliar terminology.
Devise a team strategy to tackle the problems effectively and efficiently!
Why should I participate?
For the fun of it! The competition will be thrilling and
dynamic - similar to a game. You can look forward to
many exciting elements, like progressive unlocking of
problems, live leaderboards, and
Half Hour Rush. The competition will require lots of collaboration and is designed to stimulate fruitful and enjoyable discussions of physics. Hopefully, you will find our problems innovative, interesting and intellectually stimulating!
You also stand a chance to win awards and glory!
Are you excited?

Once you have chosen your dream team and decided on a team
name, we just need one member of your team to fill in the registration form!
There is no limit to how many students from each school can participate. So, don't be shy - go ahead and register!
The deadline for registration is 11 April 2025 (Friday), at 11.59 PM. Only one registration is required for each team i.e. it is not necessary for every team member to fill up the registration form.
A few weeks after the registration deadline, we will send more information to your registered email address - check your spam folder too! Please email us at contact@sgphysicsleague.org
if you still have not heard from us by 1 May 2025.

If your dream team comprises students from
different schools…
Such an arrangement is perfectly fine by us!
Make sure you register as a team with your team members from other schools.
For example, suppose your team comprises 2 members from school X, 2 members from school Y, and 1 member from school Z. One member of this team simply fills up the registration form and includes all 5 of these students in the form. The admin personnel in the OT will receive this information and compile a list of students participating in SPhL to send to the respective schools (in this case, school X, school Y and school Z). Each school will be informed that these students will be participating with team members from other schools.

If your dream team comprises students from
different levels…
This is permitted,
as long as your team members' categories do not
mix.
In other words:
done Secondary school students from different levels are permitted to join SPhL (Junior) as a single team.
done Junior college or [NEW!] Polytechnic students from different levels are permitted to join SPhL (Senior) as a single team.
close However, a team cannot comprise both secondary school and junior college / polytechnic students.
As long as these conditions are met, having members from different levels is permitted.
No special procedure is needed for registration here, simply indicate each team member's level in the registration form accurately.

Is it better to join as a team of 3, 4, or 5?
We definitely encourage teams of 5. There is
tremendous strategic benefit to having more members!
With more hands and minds at work, more problems can
be conquered, and consequently, more points scored,
increasing your chances of an award.
Besides, how often do you get such a great excuse to talk all-things-physics and “jam” with fellow physics enthusiasts? As the adage goes: the more the merrier!

We are a passionate group of youths who have enjoyed
various physics olympiads and tournaments back in our school days.
We are excited to organise SPhL as a novel way to inspire
interest in physics, and to promote lively discussion of physics.
Most of all, we want students to enjoy the process of thinking about
and talking about challenging physics puzzles.
SPhL is supported by the Institute of Physics Singapore (IPS) and the Singapore Ministry of Education (MOE). We are also grateful to Micron for its sponsorship and to the Singapore University of Technology and Design (SUTD) for co-organising our first-ever physical event, the SPhL Grand Finals.
