Biology League

Who?

Anyone currently enrolled in a junior college, polytechnic or equivalent is eligible.

Form a team of 3–5 to register!

When?

It's on .

You'll be competing in real time from (4 hours).

Where?

The Singapore Biology League (SBL) will be held online.

Meet up with your team or compete from home!

Two teams of animals and plants high-fiving each other.

Solve problems as a team!

Challenge yourself with refreshing biology problems that are sure to get you thinking. We recommend forming a diverse team in order to tackle any problem that comes your way!

Read the full rules
A tree, a skink and a pigeon working together at a desk to solve a problem.

It's more than just memory work.

No one likes to mug for biology exams, so we made SBL an open book contest! You have to think critically to solve our problems that can range anywhere from precise molecular processes to complex ecological systems.

Try our sample problems
A pangolin holding the team's points as they soar up the leaderboard.

Compete on a live leaderboard!

Pit yourself against other teams by answering questions to earn points. Strategise within your team to solve as many questions correctly, as quickly as possible.
