Biology and Science Tutoring for Ontario Grades 9 to 12

Two students climb a DNA helix staircase rising from stones marked atom, magnet, planet and flask toward a university building, one holding a microscope.

We match your teen with a graduate-level tutor who finds where SBI3U, SBI4U or Grade 9 and 10 science marks slip and rebuilds those topics, all semester.

SBI3U · SBI4U · One-on-one

From $47.50/hr · Lessons usually start within 2 to 3 days

Where biology and science marks are usually lost

And how a tutor fixes them

The amount of biology to learn jumps in Grade 11. SBI3U covers genetics, evolution and animal body systems, and SBI4U goes molecular: biochemistry, metabolism and gene expression. Many nursing and life science programs require SBI4U. We also tutor every unit of Grade 9 and 10 science. A slipping mark usually comes down to a few fixable topics, not a student who is bad at science.

Genetic crosses in SBI3U

Metabolic pathways in SBI4U

Chemistry and optics in SNC2D

Dihybrid and sex-linked crosses chain several steps, so one wrong gamete or misread symbol throws off the final ratio. A tutor rebuilds the setup from alleles to gametes to Punnett square, then practises mixed problems until they are routine.

Cellular respiration and photosynthesis ask students to track carbon, electrons and ATP through several stages in different parts of the cell, and the stages blur together. A tutor builds one clear map of each pathway, then drills exam questions.

Grade 10 science changes topic every few weeks, and marks usually drop in chemistry (naming compounds, balancing equations) and optics (ray diagrams for mirrors and lenses). A tutor rebuilds each skill step by step, then practises test questions.

The Ontario biology and science courses we tutor

Ontario curriculum, grade by grade

SBI3U

Grade 11

Grade 11 Biology

Diversity of living things, evolution, genetic processes, animal structure and function, and plant anatomy and growth. Gaps in its genetics unit tend to resurface in SBI4U.

SBI4U

Grade 12

Grade 12 Biology

Biochemistry, metabolic processes, molecular genetics, homeostasis and population dynamics. Many nursing, life science and health science programs require it.

SNC1W

Grade 9

Grade 9 Science

STEM skills plus biology (ecosystems and climate change), chemistry (atoms, elements and compounds), physics (electricity) and space exploration. It leads into SNC2D.

SNC2D

Grade 10

Grade 10 Science

Tissues, organs and systems of living things; chemical reactions; climate change; and light and geometric optics. It is the prerequisite for SBI3U, SCH3U and SPH3U.

What Families Say

Biology and science tutoring questions, answered

How quickly can my child start with a biology or science tutor?

Tutoring can usually start within 2 to 3 days. Request a Tutor online with one short form, or book a free, no-obligation consultation if you would like to talk first. Your child keeps the same tutor all semester.

Who are the biology and science tutors?

Our biology and science tutors are Master's, PhD and medical students and graduates from uOttawa and Carleton, with backgrounds in biology, neuroscience, health sciences and biomedical engineering. Every tutor is vetted in three steps, and we switch tutors if the fit is not right.

Are lessons online or in person?

All lessons are live online and one-on-one. Tutor and student work on an interactive whiteboard, which suits Punnett squares, labelled body-system diagrams and metabolic pathway maps. Each session is recorded, and a summary and notes are shared afterwards.

Does SBI4U matter for university admission?

For many programs, yes. Many Ontario nursing, life science and health science programs require SBI4U, and a required course counts in the admission average even if it is not among the student's top six marks. Requirements vary by program, so check each one early.

When should we start biology or science exam prep?

Start at least three weeks before the final, ideally four. From 2026-27, SBI3U and SBI4U end with a mandatory written exam worth 25% of the mark (20% in SNC1W and SNC2D). Prep begins with a full-course diagnostic, then targets the biggest gaps with spaced review.

Can the tutor help with the chemistry and physics units in Grade 9 and 10 science?

Yes. SNC1W and SNC2D mix biology, chemistry, physics and Earth and space science, and sessions follow whichever unit your child is in, from atoms and circuits to optics and climate change. Tutors also help with unit tests, lab reports and homework.
