Your teenager spends hours studying Chemistry. They know the definitions and have highlighted every page of their notes. Yet the next test contains an unfamiliar question, and their mark falls again.
When your child is in Grade 12, it can feel as though there is no time to waste. For Nigerian and other African parents raising a teenager in Ontario, the course codes and university application process may add another layer of worry.
The best response begins with a specific question: What can your child explain independently, and where do they become stuck?
A student who misunderstands chemical structures needs a different plan from one who understands the concepts but makes mistakes in calculations.
What is SCH4U?
SCH4U is Ontario’s Grade 12 university preparation Chemistry course. It covers organic chemistry, the structure and properties of matter, energy changes and reaction rates, equilibrium, and electrochemistry.
The course builds on Grade 11 Chemistry. It also asks students to solve problems, investigate chemical processes and communicate their reasoning. Reading notes repeatedly may help with vocabulary, but it is rarely enough preparation for every kind of question.
Ask your child for three things: their course outline, a recent marked test and one assignment they found difficult. Those will show you where to start.
Why a student can study hard and still lose marks
Look at the type of mistake rather than only the score.
They recognise an example but cannot apply the idea
Your child can follow a worked solution in their notes. When a test changes the wording or the information provided, they do not know which principle to use.
They need practice deciding what the question is asking before they begin calculating.
Earlier Chemistry or Maths skills are uncertain
Grade 12 work becomes harder when a student is still unsure about rearranging an equation, interpreting units, balancing a reaction or using ideas from Grade 11 Chemistry.
More SCH4U practice questions may not fix an earlier gap. A tutor or teacher needs to find it first.
They remember vocabulary but cannot explain a process
A student might define equilibrium but struggle to explain how a change to a chemical system could affect it. Ask them to describe the idea aloud, without reading from their notes.
If their explanation stops after one memorised sentence, they may need to build a clearer model of what is happening.
They lose marks when presenting an answer
Sometimes the method is partly correct, but a calculation has no units, a conclusion lacks evidence or the written explanation does not answer the question asked.
A marked test can help distinguish weak understanding from weak communication.
A practical way to review a disappointing test
Sit with your child and choose three questions, not the entire paper. For each one, ask:
- What was this question asking?
- What did you try first?
- Where did your method stop working?
- What does the teacher’s feedback tell you?
- Could you solve a similar question without looking at the answer?
Write the recurring issue in plain language. For example:
- “I cannot identify the functional group from the structure.”
- “I know the equilibrium idea but cannot apply it to a new situation.”
- “I set up the calculation but make mistakes with units.”
That is a more useful starting point than “I need to study all of Chemistry again.”
How should your teenager study between lessons?
Encourage them to spend less time only rereading and more time retrieving and using what they have learned.
After reviewing a topic, close the notes. Ask your child to explain the key idea, sketch a process or attempt one new question. Then they can reopen the notes and identify what they missed.
Keep a short error log with three columns: question type, mistake, corrected reasoning. Before the next test, your child can revisit the patterns in their own work.
This should remain your teenager’s learning plan. Parents can help them organise it and find support, while giving them room to take responsibility for their progress.
What should parents ask the school?
Ask the Chemistry teacher which topics are causing the most difficulty and what improvement is realistic within the remaining course time. A guidance counsellor can help your teenager check how SCH4U fits the specific postsecondary programmes they are considering.
Avoid assuming that every university or programme has identical admission requirements. Check the actual requirements and deadlines for your child’s choices.
If your teenager is disappointed or embarrassed by a mark, begin with what the work shows they can do. Then agree on one skill to address next. A clear plan is easier to act on than repeated reminders to “work harder.”
When can a Chemistry tutor help?
A useful SCH4U tutor should begin with the course outline and marked work. They should ask your child to explain their reasoning and identify whether the difficulty lies in the underlying concept, the calculation, the wording or the final explanation.
Lessons can then target the gap, give your teenager a chance to solve new problems independently and revisit the skill to check that it has been retained.
Ask for progress updates that name the topic and the next step. “We covered Chemistry” tells a parent very little. “Your child can now identify these structures independently but needs more practice applying the reaction concepts” is more useful.
