Online Science Tutoring for Ontario Students
Science doesn't build the way math does. A student can be strong in Grade 10 science and still find Grade 11 chemistry feels like an entirely different subject, because biology, chemistry and physics each restart their own content most years. That's usually the moment a parent starts looking for help, not because their child got worse at science, but because the course changed what it's actually testing. TutorBoost matches Ontario students with tutors who specialize in the specific science they're taking right now, not a general "science helper."
Start With a Free Trial SessionScience Tutoring by Grade
We tutor science from early elementary curiosity through Grade 12 university-preparation courses, following the Ontario curriculum your child is actually being taught. Sessions are matched to the specific strand a student is working through, so a Grade 11 chemistry session looks nothing like a Grade 11 physics one.
Elementary Science
Hands-on sessions in science and technology, life systems, matter and energy, and earth and space systems, building the observation and reasoning skills every later science course depends on.
Middle School Science
Sessions build core STEM skills and a deeper look at matter and energy, plus the more formal lab habits students will lean on once high school science splits into separate subjects.
Integrated Science
The last two years biology, chemistry and physics are taught as one course. Getting comfortable here matters, since Grade 11 splits the same content into three separate subjects at once.
Biology
Cells, genetics, human systems and evolution. Grade 12 biology carries a heavy recall load on top of the concepts, which is where most students ask for extra support.
Chemistry
Bonding, stoichiometry, organic chemistry and chemical equilibrium. Real equilibrium chemistry shows up outside the classroom too, see our piece on ocean acidification for one example.
Physics
Kinematics, forces, energy and circuits. Physics leans on math skills more than any other science, our math tutoring page covers the related course support.
Science doesn't build in a straight line the way math does: a strong Grade 10 mark doesn't guarantee an easy Grade 11, because biology, chemistry and physics each restart their own content. See all subjects and tutoring plans.
Where Ontario Science Students Actually Get Stuck
Science struggles rarely come from one bad topic, they come from a course changing what it rewards. A student who thrived on memorization can suddenly need to reason through a problem instead, and that shift catches strong students as often as struggling ones. Here's where it happens most in the Ontario curriculum.
The jump from SCH3U to SCH4U
Students who did well on recall in Grade 11 chemistry often watch their mark slide in Grade 12, not because they got worse, but because SCH4U demands concept, calculation and mechanism at the same time.
Organic chemistry naming and reactions
The unit most SCH4U students flag first. The naming rules feel arbitrary until a tutor shows the pattern behind them, at which point most of the difficulty disappears.
Stoichiometry and mole calculations
This is where chemistry quietly turns into a math problem, and students who are otherwise strong in the subject stall because the arithmetic gets in the way of the concept.
Chemical equilibrium
An abstract idea that's easier to grasp with a real example, like how the ocean's own chemistry works. See what ocean acidification actually is.
Grade 12 biology's recall load
Cell processes, genetics and human systems arrive with a heavier volume of material than most students expect, and cramming it close to a test rarely holds up.
Physics: a math problem in a lab coat
Kinematics and forces are usually algebra and trigonometry wearing different labels. Students who are shaky in Grade 11 or 12 math often feel it first in physics.
How Science Tutoring Works
Sessions are built around the student's own coursework, not a separate curriculum they have to learn alongside school. That matters more in science than in most subjects, since a textbook explanation and a classroom explanation don't always use the same wording for the same idea.
Create a profile and tell us the course
Share the grade, the course code and which strand, biology, chemistry or physics has been difficult lately. The more specific the starting point, the faster the first session becomes useful.
Get matched with a science tutor
Our matching process pairs students with a tutor suited to their grade, subject and learning style. You can also browse tutor profiles and choose directly.
Bring your own work to the session
Homework, lab reports, review sheets, past tests, sessions follow what the student is actually being marked on, including the scientific writing that many students find harder than the tests themselves.
Meet online, on a schedule that fits
Sessions run live over Google Meet or Zoom in a monitored, professional environment. Availability, scheduling and rescheduling are all handled through the student portal.
Choose Your Tutor Level
Three tutor levels so you can match the support to the stakes. A Grade 8 science project and a Grade 12 chemistry final are not the same problem.
Junior Tutor
A knowledgeable educator with strong subject expertise and foundational teaching experience in their field.
Senior Tutor
Advanced subject expertise and significant teaching experience, with proven student success and outcomes.
Lead Tutor
A highly experienced educator with exceptional qualifications and a track record of outstanding student outcomes.
Monthly fixed plans include up to 6 sessions per week, a same-tutor guarantee and sibling sharing. Hourly booking stays flexible on course, tutor and timing.
Built Around the Ontario Curriculum
Our tutors work from the student's own unit cells, stoichiometry, kinematics, rather than a generic syllabus, so sessions reinforce what's being taught in class rather than introducing a second, competing explanation. Students should confirm course prerequisites with the Ontario Board of Education before registering.
Because sessions are fully online, students across Ontario can access the same tutors regardless of where they live.
