Learn Our Story →🎨 What Makes BioGuide Stand Out
🌱 Our Plant Computational Biology Website
This is a completely indigenous resource for practicing Plant Computational Biology, which although was only in the practicals for IBO 2026, is still relevant.
🧬 IBO 2022 Bioinformatics Practical Simul
This is another indeigenous website we created to help with bioinformatics practicals. It is a dynamic creation helping people seriously commit to IBO preparation.
📊 Practice Tests
Full-screen, timed, with subject breakdown and personalized recommendations.
🎮 BiOLudo
Our first game: a biology-trivia Ludo variant where dice get you into range, but a quiz duel decides who wins the fight.
🤝 Contribute to BioGuide
As of August 8 2026, this website has only been a one man project and we are currently assembling a team of people who think this is worth contributing to. So please help yourself!
BioGuide follows this open contribution model:
- Found an error? Open a GitHub Issue or submit a PR
- Want to add a topic? Follow the template in
handoff.md - Have a better diagram? Source it and we’ll add it
We need help with:
- Expanding our Current BiOrchive - Send an email to resourcerepository4boguide@gmail.com for this purpose.
- More and improved interactive widgets (especially for Cell/Molecular Biology)
- Adding diagrams to pages that still have placeholders
