Top Strategies for Acing Your Grade 12 Chemistry Course in Ontario
Grade 12 Chemistry Course in Ontario

Currently, chemistry has become a fascinating subject that helps us understand its nature. Unfortunately, Ontario Grade 12 Chemistry (SCH4U) is listed as one of the toughest courses in high school for many students. This course is designed for students who wish to continue their studies in the areas of science, engineering, or healthcare at a postsecondary level, and that requires considerable problem-solving skills, conceptual understanding, and practical application.
If you’ve also taken the Ontario Grade 12 Chemistry course, you might be wondering how to approach the more difficult topics you’ll meet in SCH4U, like organic chemistry, equilibrium, thermodynamics, and electrochemistry. This guide aims to optimize your high school chemistry performance, ensuring you achieve the desired marks for your university pathway during your final year of high school chemistry.
Familiarise yourself with the course requirements.
The information I provide here is based on the structure of the Grade 12 Chemistry course in Ontario, so be sure to look at that structure before immediately jumping into complex topics. The five major areas of the SCH4U curriculum are as follows:
- Organic Chemistry
- Matter and Its Interactions (Structure and Properties of Matter)
- Changes in energy and reaction rates
- An introduction to chemical systems and equilibrium
- Electrochemistry
Referring back to concepts taught in Grade 11, as each unit builds on the last it will help greatly. We should prioritise understanding these concepts over memorising principles and applying them to new problems
Start Mastering Concepts of Organic Chemistry Early
Organic chemistry is one of the hardest units of SCH4U. This unit covers the following concepts:
- A guide to naming organic compounds and drawing them
- How to Find the When Out of the Functional Groups and Their Properties
- Reactions of addition, substitution, and elimination
- Polymerisation: real-life scenarios
Since university science programs rely on SCH4U organic chemistry, it's crucial to commence early and engage in frequent practice. Flashcards will help you memorise power functional groups, draw molecular structures, and work on reaction mechanism questions as much as possible.
Use multiple study resources.
For eighth graders, class notes aren't enough.
Ontario Curriculum Documents: A document that outlines what you should include in your Grade 12 Chemistry course in Ontario.
Textbooks and Online Workshops: To cover challenging topics, use suggested textbooks, YouTube video tutorials, and interactive chemistry sites.
Practice exams and past tests or class exams: The presentation and complexity of the assessments precede the familiarity with past questions.
Ability to manage and solve problems effectively
Chemistry is equally about solving conceptual problems as well as mathematical ones. To sharpen your ability to work through problems:
- Comprehend the “why” behind all the concepts: Don’t memorise formulas; understand why they are working.
- Practice Regularly: From wide-ranging multiple-choice questions to long-answer problems, solve different types of questions.
- Break Down Problems Step-By-Step: Most chemistry problems are multi-step, multi-part solutions. Then make them into smaller components; do not be overwhelmed.
The same is true of SCH4U organic chemistry, equilibrium, and electrochemistry, all of which rely heavily on multi-step processes.
Study together or ask for help when needed.
Learning peers tend to do a lot more hands-on and fun exercises. A study group allows you to:
- Teach/explain difficult concepts to each other (teaching reinforces understanding).
- Discuss alternative approaches to the problem.
- Keep checking in and motivating yourself.
If you are struggling with certain topics, ask your teacher or tutor, or make use of online discussion forums. You need to clear the doubts at the earliest so that you can deal with the tough topics easily.
Excel in laboratories and homework
Lab work is an essential part of Grade 12 Chemistry (SCH4U) and is critical to solidifying theoretical concepts. To excel in lab assignments:
Read the Procedure Beforehand: Knowing what to do in the experiment helps eliminate errors.
Make accurate record observations: Be detail oriented and neat in your note-taking.
Think Carefully About Results: Emphasise the relationship between results and theory and explain why your results came out the way they did.
Labs are also a part of your overall mark, so treating them seriously can help your final mark as well.
Manage Your Time Effectively
Managing your time is important, as you may have a heavy course load, university applications to work on, and extracurricular activities. Here’s how:
Establish a Study Schedule: Split chemistry over multiple days each week rather than cramming before exams.
Focus on Tough Topics: Give extra attention to areas that you struggle with.
Use active study techniques—do not passively read; summarise notes; try to teach yourself the concepts; and do lots of practice questions.
Use general study strategies to prepare for exams.
Here are some strategies to begin your review early before your Grade 12 Chemistry Final Exam.
Summary Sheets—distribute each unit to key formulas, definitions, and reaction mechanisms.
Make Mind Maps: If you are a visual learner, diagramming relationships between different chemistry topics may help.
Simulate Exam Conditions: To improve speed and accuracy, practice full-length past exams under timed conditions.
