Physics is a popular subject for science as a DSE elective. If you master this subject, you will be successful in getting into the university of your dreams. To stand out in this public DSE exam, we offer the following 5 physics improvement tips.
1. It is necessary to understand the basic theory:
One of the easiest ways to learn physics is to master the basic theory. Without a foundation, it will be difficult to do any subsequent exercises. As the saying goes, everything is difficult at the beginning, so don’t be afraid. If you have any questions, feel free to ask the teacher.
Tips: Draft a Mind Map containing all knowledge points and concepts and associate them with the problem. In this way, you can see the whole picture of the theory and help with the basic principles that they actually want to ask for every complex question in mathematics.
2. Simplifying the problem:
physics is ahard to memorizesubject, but once simplified it becomes one of the most interesting and highest scoring subjects. Sometimes you'll encounter a tough problem, remember to break it down into simpler smaller components and attack each one one by one.
3. Create Flash Cards:
When you review various topics, write down the new words/concepts you encounter, and you can write some Principles and Laws into Flash Cards. In your spare time, you can also use these Flash Cards for quick memorization. Knowledge relies on memory and is built up layer by layer like a cake. Sometimes these Flash Cards also come in handy when you're stuck solving practice questions, so why not have one ready?

"Mathematics is the cornerstone of physics",Albert Einstein said it well. In order to understand physics well and perform well in physics exams, numeracy skills are essential. Students who do better in math generally do better in physics. This is a direct relationship, working hard in mathematics is also in physics.
5. Professional physics tutor
Are you studying hard but getting no results? Why not ask the teacher. You need a dedicatedPhysics tutor, Phy tutors can help you simplify concepts so that you can understand them effectively, and there are also many notes to take, so why not. An incompetent tutor will not be able to help you. Instead, it will make you think hard and puzzle you.GETUTORThere are countless professional physics tutors who can match you with a professional tutor who truly loves physics.Immediately assign PH tutoring teachers in Hong Kong.
Summarize
No matter how hard you work, the final result depends on your interest and practice level, but as long as you work hard, God will not let you down. A good teacher can accompany you to learn and grow. In the end, I hope you will achieve 5＊＊ in physics. Physics is not difficult. Nothing is difficult in this world, as long as you are willing. Maybe what you need is a hard worker and a good teacherguide.
In addition to DSE, we also have tutors from different academic systems to choose from, providing the widest range of tutoring services.其他學制，其他學制，其他學制 physcisThere are mentors.
Eight key points for answering Physics questions:
1. Remember the basic constants.
In physics, certain forces, such as the accelerating gravity on Earth, are often represented by the same number no matter where or how they are used. Remembering the most common constants (and their units) is the most basic knowledge point, because it is usually not given to candidates in exams, so candidates need to remember it themselves. Here are some of the most commonly used constants in physics:

- Gravity (on earth): 9.81 meters/second2
- Speed of light: 3 × 108 meters/second
- Molar gas constant: 8.32 Joules/(mole × Kelvin)
- Avogadro's number: 6.02 × 1023 per mole
- Planck's Constant: 6.63 × 10-34 Joules × seconds
2.Remember the basic equations.
In addition to units, in physics, there are various equations. Forces act between many different forces in the universe, and their relationships are described by equations. Candidates only need to remember the contents of the equations and know how to use them. If the question does not provide certain information, the candidate can convert the equation to get a specific answer and then put it into the correct equation to calculate and solve the problem. Examples of some commonly used equations are:

- Velocity = Change in position/Change in time (v=dx/dt)
- Acceleration = Change in velocity/Change in time (a=dv/dt)
- Current velocity = Initial velocity + (Acceleration × time) (v=v0+a×t)
- Force = Mass × acceleration (F=m×a)
- Kinetic energy = (1/2)Mass × velocity2 (K=(1/2)m×v)
- Work = Displacement × force (W=d×F)
- Power = Change in work/Change in time (P=dW/dt)
- Momentum = Mass × velocity (p=m×v)
3.Study the derivation of basic equations.
Memorizing simple equations is one thing, understanding why they work is another.If you can, take the time to learn how each basic physics equation is derived. This gives you a clearer understanding of the relationships between equations and makes you a master of physics. Since you basically understand how an equation "works," you'll be able to use it more effectively rather than just memorizing it as a string of characters in your head.
- For example, let's look at a very simple equation:Acceleration = change in velocity/change in time,
- a = Delta(v)/Delta(t). Acceleration is the force that causes an object to change its speed. If an object is at time t 0 The initial speed is v 0, the final speed at time t is v, then it can be said that the object is moving from v 0Accelerate when changing to v. Acceleration cannot be instantaneous – it can happen quickly, but there will be some time lag between when the object travels at its initial velocity and when it reaches its final velocity. Therefore, it is concluded that:a = (v – v 0 /t-t 0 ) = Delta(v)/Delta(t).
4.Learn the mathematical skills needed to solve physics problems.
Mathematics is often called "the language of physics." Learning math well is a great way to improve your ability to solve physics problems. Some complex physics equations even require specialized mathematical skills (such as derivatives and integration) to solve. Here are just some keywords in mathematics that can help you solve physics problems, ordered by complexity:

- Pre-Algebra and Algebra (basic equations and "find the unknown" problems)
- Trigonometry (for force diagrams, rotation problems, and angular systems)
- Geometry (used to deal with problems such as area, volume, etc.)
- Pre-calculus and calculus (used to calculate derivatives and integrals of physical equations - usually advanced topics)
- Linear algebra (for calculations involving vectors - usually an advanced topic).
5.Focus on the important information in each question.
Physics questions often contain misleading "red herrings" that ignore unnecessary information as this will slow you down the ladder and complicate the problem. So, when reading a physics problem, you need to make sure that the piece of information given to you is correct and reasonable, and then identify the solution and write the equations needed to solve the problem. Then, assign each information point in the problem into the equation,

Tips: Remember to adjust to appropriate variables.
- For example, suppose we need to find the acceleration experienced by a car as its speed changes over two seconds. If the car weighs 1,000 kg and starts moving at 9 m/s and ends at 22 m/s, we can say v 0 = 9 m/s, v = 22 m/s, m = 1,000 t = 2 s. As mentioned above, the standard acceleration equation is a = (v – v 0 /t-t 0 ). Note that the mass of the object is not taken into account here, so we can ignore the fact that the car weighs 1,000 kilograms.
- Therefore, we will solve as follows: a = (v – v 0 /t-t 0 ) = ((22 – 9)/(2 – 0)) = (13/2) = 6.5 m/s 2
Forgetting to mark your answers or using incorrect units are mistakes of the lowest order. To ensure you get the best possible score for any question you do, be sure to mark your answers with the correct units according to the type of information expressed. Listed below are some of the most commonly used common units of measurement in physics - please note that physics questions almost always use metric/SI measurements:
7.Don't forget the small details (like friction, resistance, etc.).
Physics problems are usuallyreal world model- That is, questions simplify how things actually work, making the situation easier for the reader to understand. However, this doesn't mean you can ignore an important tip, such as friction. It can be ignored unless the question states that it was intentionally left out of the question. If questions are not explicitly excluded and you have sufficient information, be sure to indicate them in your answer or ask your examiner for instructions.
- For example, suppose a problem asks you to find the acceleration of a 5-kg block along a smooth floor when it is pushed with a force of 50 Newtons. Since F = m × a, the answer seems to be as simple as solving for a in the equation 50 = 5 × a. However, in the real world, friction impedes an object's forward motion, effectively reducing the force with which it is pushed. Give the answer that excludes this friction force from the problem and gives the block accelerating slightly faster than it actually does.
8.Check your answers carefully.
A moderately difficult physics problem can easily involve a dozen mathematical calculations. Miscalculating any of these may result in your answer being incorrect, so pay close attention when doing your calculations.
Tips: If you have time, please check your answers carefully at the end.
- While simply redoing your calculations is one way to check that you answered a math question correctly, you can check your answers by using common sense to relate your questions to real life.
- For example, if you try to find the momentum (mass "Forward" direction is opposite). Therefore, if you get a negative answer, you may have made a mistake somewhere.
FAQ
1. PhysicsTutoring students and how to start fromPhysicsBenefit from tutoring?
Tutors provide private tutoring and professional assistance to meet the test study needs of your students and parents. Grades will improve, thinking will be sharper, and learning will be more efficient, but more importantly, his/her self-confidence and abilities will increase.
Other benefits include:
- Improve candidates' views on school and physics. School and exams are not a battle that is difficult to win, but an opportunity to express themselves, and every student has this potential.
- Finish your physics homework faster because finishing it faster will give you time to do other things.
- For more effective study habits, there are ways to learn. If you can't do it, you just haven't found the right method yet.
2. Who will use the recommended physics tutors?
As long as you have needs, anyone can come to consult or use physics tutors. Not only the recommended physics tutors, but also other registered tutors are welcome on the platform.
Demanders such as:

Tutor fees depend on the tutor's teaching experience, the student's level of study and subject area, etc. Once we confirm a suitable physics tutor and class time, we will proactively contact you and provide the contact information and background of the physics tutor. The entire process usually only takes a few hours.
6. How long does the physics tutoring class last?
Most students and physics tutors will take 1.5 to 2 hours of tutoring. Firstly, the transportation and time arrangements of both parties will be better; secondly, students can learn more deeply, and at the same time, it will not be too burdensome for students.
7. How many times a week should we have physics tutoring?
This depends on the student's current level, goals for improvement, and schedule. Most physics students arrange 2 to 3 periods of physics tutoring, but progress can be seen in every class.
8. How long will it take for me to make progress and see results?
It also depends on the student. Results from physics tutoring come over time and with student effort - on average, significant improvements are seen after 3 months. A major goal of physics tutoring is to provide students with the tools to succeed. Developing talent and learning takes time, but once learned, these habits will have a positive impact on students throughout their academic lives.
9. PhysicsWhere do private tutoring sessions take place?
Generally, physics tutoring will be conducted at the student's home. If it is not convenient, you can choose online tutoring such as ZOOM. When using ZOOM at home, students will feel comfortable and relaxed. In a familiar environment, their brains will be calmer and clearer, so they will be more open and receptive to physics tutoring and learning.
10. Do physics tutors from GETUTOR Hong Kong Tutors Association assign extra homework to students?
Physics tuition classes between students and physics tuition tutors are created exclusively to meet the needs of students. If a student needs extra practice, you can ask the tutor to schedule additional homework. But please note that homework is to consolidate what you have learned and deepen your understanding, not more is better.
11. PhysicsWill tutors contact parents?
We generally recommend that tutors contact parents. Physics tutors can notify parents about student progress and alert areas where your student may need additional help. The three-way cooperation between parents, tutors and teachers is the cornerstone for students to achieve their ideal goals.
12. How can I improve the tutoring effectiveness of physics tutoring for students?

大學 Physics 係一個全新世界
好多學生讀完 DSE 物理攞到 Level 5**，以為入大學 Engineering 或者 Physics Major 會得心應手。上到第一堂就發現 —— 大錯特錯。大學 Physics 同 DSE 根本唔係同一回事。
根據 GETUTOR 後台 2024-2026 年大學物理補習配對紀錄，樣本約 165 宗，平均配對時間去到 5.3 小時*，係所有大學理科類別裡面最難配。因為識教大學 Physics 嘅 tutor 本身就少，多數係讀緊 PhD 或者 Master 嘅研究生。
大學物理補習試堂繼續率維持 78%*，但一旦啱 tutor，呢個比率會去到 91%*。關鍵係 tutor 要識由 DSE 過渡到 Calculus-based Physics 嘅思維轉變。
Calculus-Based Physics 點樣攻？
「Mr. W（按導師私隱要求使用化名，導師資歷已獲 GETUTOR 平台認證）—— 香港科技大學哲學碩士畢業（主修物理），本科亦喺 HKUST Physics 一級榮譽。本身係研究 condensed matter physics，私補年資 6 年，主力補 HKU、HKUST、CUHK 嘅 UG 學生。累計教過超過 28 個大學 Physics 學生，當中 9 個原本 CGPA 2.8 以下，後來升到 3.3 以上。教學風格偏向由 derivation 帶入，唔係齋背公式。」
Mr. W 分享：「DSE 物理嘅 F=ma、E=mgh 呢啲公式係靜態嘅，一個 scenario 配一條公式。但大學 Physics 要你用 calculus 嚟 derive 成條公式。例如 work-energy theorem，你要識寫 W = ∫ F·dx 呢條積分，先可以應付 variable force 嘅情況。」
佢嘅教法分三步：先畀學生複習返 DSE 嗰條公式，跟住解釋呢條公式背後其實係 calculus 嘅 special case，最後示範 calculus 點樣 generalise。呢個 approach 令學生明白 DSE 學過嘅嘢冇浪費，但同時 upgrade 到大學 level。
另一個核心技巧：Vector analysis。DSE 只用 scalar components，大學會要求你識用 unit vector（î, ĵ, k̂）寫所有嘢。Mr. W 建議每個學生做完一條 mechanics 問題後，要用 vector form 再寫一次作為練習。

GETUTOR 導師防伏貼士
好多大學生搵補習嗰陣，見到「HKU Physics 畢業」就落訂，結果 tutor 本科係 Applied Physics，根本冇讀過 Classical Mechanics 嘅 Lagrangian formulation。Mr. W 指出：「唔同 major 嘅 Physics curriculum 係唔一樣。如果你讀 Theoretical Physics，搵個 Applied Physics 出身嘅 tutor 會教唔到你 Hamiltonian。搵 tutor 一定要問清楚佢讀過咩 course。」
另一個伏：以為做 past paper 就搞掂。大學 Physics 唔似 DSE，past paper 嘅題目年年唔同，靠操卷攞 A 嘅策略完全失效。真正有效嘅係做 textbook 後面嘅 problem sets。例如 Griffiths 本 Electrodynamics、Taylor 本 Classical Mechanics，呢啲書嘅題目先至係大學考試嘅 source。
仲有一點：唔好係學期尾先搵 tutor。大學物理嘅概念要 build up，如果你 Lecture 5 已經唔明，去到 Lecture 10 已經完全冇得救。Mr. W 建議由 Week 2-3 見到跟唔上就要搵 tutor，唔好等 midterm 之後先 panic。

Case Sharing
個案分享（已匿名處理）：一位 HKUST Physics 二年級學生，第一學期 Electromagnetism I 只有 C+，成個 Maxwell Equations 嘅 derivation 完全唔識做。經過大約 18 堂私補後，第二學期 Electromagnetism II 最終攞到 A-。Mr. W 嘅重點係頭 5 堂唔碰課程內容，淨係補返 Vector Calculus（div、curl、gradient）呢啲 prerequisite，搞掂之後後面啲課程就順晒。

FAQ
讀 Engineering Major 都要補 Physics 嗎？
要。Engineering 一年級嘅 General Physics 難度雖然冇 Physics Major 咁深，但如果你 DSE 物理底唔紮實，一開學已經追唔上，要趁早搵 tutor。
大學物理最容易卡邊度？
Maxwell Equations 同 Lagrangian Mechanics，佔咗區內配對需求約 42%。因為呢兩個 topic 需要 PDE 同 Variational Calculus 嘅 prerequisite，好多學生根本未學過。
私補同 tutorial session 最大分別係咩？
最大分別係深度。Tutorial 淨係講解答，唔會幫你 build 概念。私補可以度身改 curriculum，填補你喺 lecture 聽唔明嘅 gap，甚至幫你 prep 緊張嘅 exam。
