1. Learn from Friends and Teachers


2. Tự ghi chú những điều cần nhớ và Tự học ở nhà
Trong quá trình học và làm bài tập, giải đề thi, có rất nhiều những điểm đáng lưu ý và đặc biệt mà bản thân chúng ta phát hiện ra. Những lúc như vậy chúng ta nên ghi chú cần thiết vào một cuốn vở hay cuốn sổ nào đó, để sau này ôn tập lại hay cần tìm đến mà học. Đó cũng là một cách giúp chúng ta nhớ kiến thức lâu hơn.
Tự học vẫn là cách học tập hiệu quả nhất. Giáo viên chỉ là người truyền đạt kiến thức và kinh nghiệm, đồng thời giải quyết giúp bạn những vướng mắc khi bạn cảm thấy khó khăn. Bản thân bạn chính là sự quyết định. Vì vậy, ngoài việc xem bài kỹ trước khi đến lớp thì sau những tiết học bạn cũng phải học và áp dụng vào làm bài tập ngay sau khi về nhà.
Trước hết, phải ghi nhớ kỹ lý thuyết sau đó vận dụng vào bài tập. Chăm chỉ làm đi làm lại những dạng bài tập trong sách giáo khoa cũng như nghiên cứu thêm những sách tham khảo bạn sẽ rút ra được cách làm cũng như các bước giải bài tập hóa. Từ đó, việc giải một bài tập sẽ trở nên đơn giản hơn. Vì kiến thức về môn hóa rất nhiều và khó nhớ, nên bạn phải làm sao để hệ thống lại một cách gọn gàng, biến những kiến thức của thầy cô và sách vở thành kiến thức của chính mình.


3. Create study groups
Group study can create an effective learning environment. If you're working alone, you might struggle with challenging exercises, but with a group, each person brings their unique insights, which can lead to different ways of solving problems and approaching exercises. However, the downside of this approach is that if one member lacks motivation or discipline, the study session can become unproductive.
There are many effective study methods for Chemistry. However, the key is the dedication and determination of each student. If you have already set your goals for the future, start working hard today. Don't skip any lessons, whether easy or difficult.
Be diligent in your studies and complete your assignments every day. Additionally, make sure to equip yourself with helpful study tools like reference books, internet-connected devices, etc., so you can expand your knowledge and learn from the advice and experiences of those who came before you. Good luck!


4. Use effective memory techniques like Mind Map diagrams
How can you remember the entire periodic table? Or recall every historical event in a textbook? Follow these steps: Create an outline, rehearse mentally, and write it down. This is especially important for formulas, theorems, and definitions. While writing, focus only on the key points so that when you review your notes, you can recall the content without needing to open the book.
Avoid excessive notes that waste time and energy. The key is to combine methods like mental rehearsal, note-taking, and outlining, making sure to study in a way that helps you memorize faster. Use effective memory techniques like Mind Map diagrams to consolidate your learning.
Focus on understanding the core knowledge. This often involves specific categories like concepts, hypotheses, laws, and theories. When learning, grasp the essence of the subject and recognize how to apply concepts, laws, and theories in solving real-world problems. Additionally, practice to develop problem-solving skills (exams are a form of real-world problem-solving).
There are two approaches: applying formulas and thinking creatively and flexibly. During revision, pay attention to both: vertically (within the same type of problem or field) and horizontally (across different subjects that are related). Once you've completed the theory, challenge yourself with questions related to the material to assess your understanding. This helps retain information and expand your working memory capacity.


5. Learn Smarter
Study in intervals. Long, non-stop study sessions without breaks won't help you absorb information efficiently. To learn effectively, take breaks during study time. Try studying in 30-minute blocks with 5-10 minute breaks in between. If you notice a decrease in focus, it may be time to stop studying for the day or switch to another subject. During breaks, do something relaxing that doesn't require much concentration, like stretching or taking a walk.
Self-testing. Use flashcards, quizzes, and practice tests to enhance your learning. You'll retain knowledge better by taking practice tests rather than just rereading the material. Try making flashcards for self-testing. You can create quizzes or ask yourself questions, or use past exam questions. Consider doing a practice quiz or mock test beforehand. Focus on the most difficult topics, as these need your attention the most while studying.
Engage as many senses as possible. Some people have better memory retention when multiple senses are involved in the learning process. A way to incorporate more senses is by rewriting and reading aloud your notes. This method uses various senses and can help you retain information more effectively.
Play memory-boosting games. Try using songs, acronyms, or memory tricks to learn information. For instance, if you need to remember the musical notes EGBDF, you could create a mnemonic such as “Every Good Boy Does Fine.” Memory games don't work for everyone, so feel free to skip them if you find them difficult to apply.


6. How to Excel in Chemistry Exercises
To excel in chemistry, students need to master chemical properties, synthesis methods, and understand the structure and physical properties while paying attention to chemical reactions.
- Writing reaction equations: You must be familiar with the chemical properties of substances and consider what other reactants can interact with these compounds.
- Reaction sequences: Master both chemical properties and synthesis, understanding the relationships between substances, changes in carbon chains, etc. Along with reaction conditions, deduce the formulas of substances (especially for difficult problems), ensuring equations are balanced and conditions are noted when necessary.
- Identifying chemicals: Know the reagents required, their indicators, and write the reaction equations with the corresponding indicators.
- Explaining phenomena and demonstrating: Write out the reactions that occur at each stage, noting the formation of precipitates, evaporation, color change, smell, etc.
Exercises on substances: Names: Understand how to name substances (some substances have multiple names: common names and international names).
- Physical properties: Generally, we focus on remembering the state (solid, liquid, gas), color, solubility, smell, taste, boiling and melting points, etc. Structure: Understand the structural features of each compound and the bonding within its molecules. Be able to write the structural formula for each compound.
- Chemical properties: Based on the structural features, deduce basic properties. For typical substances, consider what reactions they can undergo, what other substances they can react with to effectively retain and learn chemistry.
- Synthesis: Understand the general methods of synthesizing compounds. For each specific compound, besides general methods, know the unique methods for its synthesis. Be familiar with the raw materials used for synthesizing these substances.
- Applications: Remember the uses of each compound and relate them to real-life situations.


7. Master the Knowledge in Textbooks
Nowadays, students often search for reference books, guides, or university exam papers to study, without realizing that textbooks are one of the most valuable resources. Although they mainly provide basic theoretical knowledge, it’s important to understand that these fundamental concepts form the foundation for faster calculation formulas or solving more complex exercises.
Textbooks will provide you with the essential knowledge to follow. Therefore, make sure to choose a reliable textbook that covers all the important concepts. Avoid looking for reference books. A good way to find textbooks is by visiting university bookstores or those recommended by your favorite professors.
Textbooks are materials created to teach and learn in schools. The term “textbook” is also used more broadly to refer to standard books for a specific subject area. Textbooks are categorized based on their target audience or subject matter, and their publication is typically handled by specialized publishing houses.
Furthermore, a large portion of the university exam questions are theoretical, and the answers or knowledge needed are often found in textbooks if you carefully study each section and topic, especially the reference materials at the end of each lesson. Therefore, don’t look too far for answers; everything you need is right in front of you. Textbooks are a reliable source of material for your studies. Hence, adopting effective study methods based on textbooks will help you excel in chemistry.


8. Practice various types of exercises
Chemistry is unique in that it involves many different types of exercises, each requiring a different approach depending on the individual. Practicing various types of exercises will help you become more flexible and quick when facing different types of problems.
To excel in chemistry, you need to master the theoretical concepts, definitions, laws, and rules prescribed in the curriculum. Additionally, observe experiments and natural phenomena in the real world, as chemistry is closely connected to real-life situations. Gradually, you will accumulate knowledge.
Handling information: try to conduct experiments on your own to draw conclusions or make important observations. Apply what you've learned to answer questions or solve problems, and apply it in real life to deepen your understanding of the subject (this is the ideal way to study chemistry). To be good at chemistry, you need to know how to study and remember in a selective and logical way: memorizing chemistry through rote learning is very hard, understanding is key.
Therefore, to achieve high results in this subject, you should explore various types of exercises in different books, solving them on your own first, and then reviewing the solutions in the book to improve your skills. This will help you identify the most efficient way to solve problems by comparing different methods and their advantages and drawbacks.


9. Complete exam papers and grade them yourself
To evaluate your learning progress, you need to put yourself in a specific exam situation and solve the test independently. There are many mock exams held nationwide in high schools, so finding exam papers is not difficult.
You should start with easier exams and gradually move to more difficult ones, complete them within a set time limit, and then grade them yourself to identify what you've mastered and what needs improvement. Afterward, focus on areas where you struggled, think through them again to see if you can solve them, and review the theoretical questions you answered incorrectly to check if your understanding is solid. This will help you learn from your mistakes.
To excel in chemistry and score high on chemistry exams, it's essential to master the theory, and be skilled in calculations (applying formulas, solving reaction equations, setting up and solving systems of equations, etc.).
List all the data provided in the test (such as values, relationships between reacting substances, conditions for reactions, etc.), and the test's requirements. Define the unknowns (usually molar quantities, or general formulas). Write out all the chemical equations that occur (be sure to balance them, include any conditions where needed). Establish the relationships between the test data and the required outcomes, set up the system of equations, and apply calculation methods (such as the average method, substitution, etc.) using basic chemical laws (mass conservation law, charge conservation law, etc.) to solve the problem.
