Online IB Biology Tuition in Singapore: One-to-One and Small-Group Tutors for Biology SL and HL

IB Diploma Biology, first assessed in 2025, is organised around four themes, each studied from molecules up to ecosystems, so students learn to connect ideas across the whole course. onlinetuition.sg matches IB students in Singapore, including IP students on the IB route, with Biology tutors for live online lessons, one-to-one or in small groups, at SL or HL.

About IB Diploma Biology

IB Biology is taught at standard level (SL) or higher level (HL), and HL adds topics of its own and more depth within others. The syllabus is a grid: four themes, each looked at across four levels of biological organisation.

Themes
Unity and diversity · form and function · interaction and interdependence · continuity and change
Levels of organisation
Molecules · cells · organisms · ecosystems
Paper 1
Paper 1A, multiple-choice questions, and Paper 1B, four data-based questions across the themes: 1 h 30 min at SL and 2 hours at HL
Paper 2
Short-answer and extended-response questions, in 1 h 30 min (SL) or 2 h 30 min (HL)
Internal assessment
The scientific investigation, in which students answer a research question of their own, worth 20% of the grade
Exam sessions
May and November

HL-only topics include muscle and motility, chemical signalling and gene expression.

Common Challenges IB Biology Students Face

Thinking Across the Grid

Questions can join themes and levels, such as linking the structure of a molecule to how a whole organism is adapted.

Four Data-Based Questions

Paper 1B sets four data-based questions spanning the themes, with graphs and tables to interpret.

From DNA to Protein

DNA replication, protein synthesis, and mutation and gene editing, explained in the right sequence.

Physiology in Detail

Gas exchange, transport, neural signalling and the integration of body systems, each with structures to name and explain.

Ecology and Evolution

Populations and communities, energy and matter in ecosystems, natural selection and climate change, all of which can appear in data-based questions.

Designing the Investigation

Turning a research question into a workable method, then analysing and evaluating the results.

How Our Online IB Biology Tutors Help

Lessons at Your Child’s Level

SL content for SL students, and the HL-only topics and extra depth for HL students.

Structures Drawn on Screen

Cells, membranes and signalling pathways drawn and labelled on a shared whiteboard as the tutor explains them.

Data Skills for Paper 1B

Regular practice reading graphs, tables and experimental results from all four themes.

Extended-Response Planning

Long answers planned to bring in ideas from more than one theme or level of organisation.

Support for the Investigation

Help refining a research question and choosing how to analyse the data; the investigation itself stays your child's.

A Plan to the Final Exams

Topic revision across both Diploma years, then timed questions before the IB exams.

IB Biology Topics Covered by Our Tutors

The four themes, with topics from each in the IB’s own words. HL adds further topics and depth.

Theme A: Unity and Diversity

  • Water · nucleic acids
  • Origins of cells · cell structure · viruses
  • Diversity of organisms · classification and cladistics
  • Evolution and speciation · conservation of biodiversity

Theme B: Form and Function

  • Carbohydrates and lipids · proteins
  • Membranes and membrane transport · organelles and compartmentalisation · cell specialisation
  • Gas exchange · transport · muscle and motility (HL)
  • Adaptation to environment · ecological niches

Theme C: Interaction and Interdependence

  • Enzymes and metabolism · cell respiration · photosynthesis
  • Chemical signalling (HL) · neural signalling
  • Integration of body systems · defence against disease
  • Populations and communities · transfers of energy and matter

Theme D: Continuity and Change

  • DNA replication · protein synthesis · mutation and gene editing
  • Cell and nuclear division · gene expression (HL) · water potential
  • Reproduction · inheritance · homeostasis
  • Natural selection · climate change

Frequently Asked Questions About IB Biology Tuition

Thinking of IB Biology Tuition?

Is IB Biology HL Much Harder Than SL?

HL has extra topics, such as chemical signalling and gene expression, more depth in many others, and longer papers. Your child's school can advise which level fits their plans.

Why Is IB Biology Organised by Themes?

The IB uses the themes and the four levels of organisation as frameworks, so ideas such as form and function come up at every level from molecules to ecosystems.

When Should My Child Start IB Biology Tuition?

Early in the first Diploma year, before the themes start to build on each other, or once tests show gaps. Starting early also leaves time for the scientific investigation.

Will the Tutor Help With the Internal Assessment?

Yes, with refining the research question, planning the method and analysing data. The final report must be your child's own work.

Getting a Tutor

How Do I Request an IB Biology Tutor?

Fill in the free form above and choose your child's IB Diploma year as the level. We'll get back to you on WhatsApp.

Do You Have Tutors for MYP Sciences?

Yes. Choose IB MYP as the level, and tell us which sciences your child studies.

How Soon Will I Hear Back?

We aim to reply within one working day, and your child starts with a trial lesson.

Lessons

How Are IB Biology Lessons Taught Online?

Live on Zoom with cameras on, with the tutor labelling diagrams and working through questions on a shared screen or digital whiteboard.

How Long Are Lessons?

Usually 1.5 or 2 hours, held at the same time each week.

What If My Child Misses a Lesson?

Let the tutor know directly. For a missed group lesson, the tutor can usually share the class recording.

Others

How Much Does IB Biology Tuition Cost?

Fees depend on the level and class size, and we confirm the fee on WhatsApp before the first lesson begins.

Are There Any Agency Fees?

No.

How Much Notice Do We Give to Stop?

One month, out of courtesy to the tutor's planning. Payment is by PayNow.
