SCH4U · Chemistry, University Preparation tutoring
One-to-one SCH4U tutoring for Grade 12 students following the Ontario curriculum. Bring your course outline and a question you found difficult: we connect the underlying ideas, show a method and help you practise it independently.
Chemistry, University Preparation (SCH4U) is listed in Ontario’s course catalogue at Grade 12. Ask your school for the current course outline and assessment expectations, then share them with your tutor.
02
SCH4U: topics to discuss
Organic chemistry, structure and properties, energy and reaction rates, equilibrium and electrochemistry. Explain how particle interactions support a macroscopic observation. For multi-step calculations, state the reaction, assumptions and units before substituting numbers. Confirm the current topic sequence and full coverage using your school’s outline and the official source below.
03
Building confidence in science
A balanced equation gives particle and mole ratios, not a direct mass ratio. Convert mass to moles first, use the stoichiometric ratio, then convert to the quantity requested. Lessons can alternate a modelled example, a question attempted together and an independent attempt so the tutor can see where understanding changes.
04
Use school feedback to guide revision
Bring a recent question, marked solution or topic checklist. Explain where you got stuck. The next practice task should check that particular skill before introducing more complexity. Tutoring supports learning; assessed submissions remain the student’s own work.
Understand it. Try it. Review it.
Put your science learning into practice.
Worked example · Moles, reactions and solutions
Find the amount in 9 g of water. Use molar mass 18 g/mol.
Use n = m/M.
n = 9/18 = 0.5.
There are 0.5 mol of water.
Common mistakes to check
Changing subscripts to balance an equation
Using millilitres in a concentration formula that requires litres
