M1 M2 comparison

M1 is better than M2? Comprehensive Comparison of DSE Extended Mathematics Subject Selection | Analysis of College Entrance Pathways

When selecting subjects in Form 3, "M1 determines M2 good? ” is one of the questions most asked by students and parents. The DSE mathematics extended unit is divided into M1 (Calculus and Statistics) and M2 (Algebra and Calculus). The course content, difficulty, scoring standards, and even the calculation method of university admissions are significantly different between the two. This article will provide a comprehensive analysis from the perspectives of course content, university requirements, personal ability matching, Band 1 secondary school subject selection trends, and the experience of past people.M1 M2 respectively, to help you make the best choice for you Extended maths Options.

M1 and M2 course content comparison table

to understand M1 M2 respectively, first of all, you need to understand the course content of the two units. M1 focuses on applied mathematics, emphasizing statistics and data analysis; M2 focuses on theoretical mathematics, emphasizing algebraic derivation and calculus depth. The following is a detailed comparison:

Course Structure Overview

Compare items	M1 (Calculus and Statistics)	M2 (Algebra and Calculus)
official name	Unit 1: Calculus and Statistics	Unit 2: Algebra and Calculus
Course Highlights	Applied Mathematics, Statistical Analysis	Theoretical Mathematics, Algebraic Derivation
Three major areas	Basic knowledge, calculus, statistics	Basic knowledge, calculus, algebra
Calculus Depth	Beginner to intermediate	Intermediate to advanced
Exclusive content	Statistics, probability distribution, data analysis	Matrices, vectors, mathematical induction

M1 course content (Calculus and Statistics)

basic knowledge: Binomial expansion, exponential function, logarithmic function
Calculus: Derivative method and its application, integral method and its application (shallower than M2)
statistics: Probability distribution (binomial distribution, Poisson distribution, normal distribution), expected value and variance, sampling and estimation, hypothesis testing basics

M2 course content (Algebra and Calculus)

basic knowledge: Mathematical induction, binomial theorem, continued trigonometric functions, mathematical constant e
Calculus: Limit, derivation method (chain rule, multiplication and division rule), application of derivation method (maximum value, rate of change), integration method (change of elements, division), application of integration method (area, volume)
algebra: Matrix operations, determinants, inverse matrices, two- and three-dimensional vectors, dot products and cross products

Question types and answer styles

project	M1	M2
Question text amount	More, need to understand the situation	Less, mainly calculated directly
Calculation steps	Moderate, but connected	longer, more steps
Interpret requirements	High, statistical conclusions need to be explained in words	Intermediate, emphasizing mathematical derivation
Error impact	One step is wrong, and all subsequent steps are wrong (chain questions)	Each step is relatively independent

Comparison of M1 M2 difficulty and scoring standards

Many people ask "M1 determines M2 Is it difficult? "In fact, the difficulty directions of the two are different and cannot be directly compared. However, obvious differences can be seen from the DSE grade distribution over the years:

Grade Cut-off Score Comparison

	M1 Cut-off (approx.)	M2 Cut-off (approx.)
Level 5**	about 93%	about 85%
Level 5*	about 85%	about 75%
Level 5	about 80%	about 65%
Level 4	about 65%	about 50%
Level 2	about 35%	about 25%

Key findings: M2 is one of the easiest subjects to obtain Level 5 among the elective subjects. A score of 65 points can already reach Level 5; while an M1 with the same score of 65 points may only reach Level 3. However, M1’s Level 2 threshold is relatively low and is suitable for students with moderate maths abilities. Every year, approximately 40% of M2 candidates obtain Level 5 or above.

"M1 is easy to read and difficult to read 5, M2 is difficult to read and easy to write 5"

This sentence is a popular saying, and it has some truth:

M1: The course content is relatively easy to understand, but the exam requirements are high. Level 5 and above require extremely high accuracy. One wrong step may affect the entire question.
M2: The course content is deeper and requires more time to understand, but the exam grading is relatively loose. Points will be counted according to the answers, and there is a large room for error.

M1/M2 requirements for different university departments

Starting from the 2024/25 academic year, the eight major universities in Hong Kong have reached a consensus to count M1 and M2 as complete elective subjects and include them in the general admission requirements of universities. This change order Extended maths Options More valuable for further studies.

General university entry requirements (from 2024)

Subject-Specific M1/M2 Requirements

Some popular subjects will have special requirements or extra points arrangements for M1/M2:

Priority is given to subjects in M2

engineering (HKU, HKUST, CUHK): M2 content (matrix, vector, advanced calculus) is highly connected with university courses
physics: Requires a solid foundation in calculus and vectors
Department of Mathematics: CUHK Mathematics Intensive Studies requires M1/M2 to be at least Level 4, and Weighting x3.5
computer science: Matrix and discrete mathematics concepts are helpful

Subjects available for either M1 or M2

Actuarial Science: HKU Bachelor of Science (Actuarial Science) requires M1/M2 to be at least Level 4
data science: M1’s statistical foundation has advantages
economics: Both are helpful, M1 statistics section or more practical

M1 Disciplines with more advantages

business school:Basics of business majors in the Department of Statistics and Probability Analysis
Social Sciences: Research methods require statistical knowledge
psychology: Data analysis and experimental design require statistical foundation

HKUST double credit courses (example)

Some courses at the Hong Kong University of Science and Technology will double the M1/M2 scores, giving students taking extended mathematics a clear advantage. This arrangement order DSE subject selection When considering M1/M2, it has more strategic value.

Suggestions for matching student abilities and interests

When choosing M1 or M2, in addition to looking at your needs for further studies, it is more important to match your own abilities and interests. The following are detailed pairing suggestions:

Suitable for students choosing M1

Interested in statistics and data analysis: Like processing data, analyzing trends, and interpreting charts
Strong English reading ability: M1 questions contain a lot of text and require quick understanding of the situation.
Pursue stability and guarantee: Level 2-4 of M1 has a lower threshold and is suitable for students with moderate mathematical abilities.
The direction of further study is business/social science: Statistical knowledge is directly helpful to business schools and social sciences
Careful and patient enough: M1 questions are closely related and require high accuracy

Suitable for students who choose M2

Interested in algebra and logical derivation: Like mathematical reasoning, proof, abstract thinking
Excellent results in Core Maths: It is recommended to choose M2 only if you are at least Level 4 or above.
Target Impact High Level (5/5*/5**): M2’s Level 5 Cut-off is relatively low
The direction of further study is science and engineering: Engineering, physics, mathematics, computer science, etc. usually give priority to M2
Willing to devote more time: M2 has deeper content and requires more practice time after class.

Quick self-test (5 questions)

Do you like processing data, analyzing trends, and mathematical deduction and proof?
Are your Core Maths scores stable at Level 4 or above?
Is your goal of further study in business/social sciences or science and engineering?
Are you willing to devote more than 4-5 hours per week to extended mathematics?
Do you pursue high level (5 or above) and stable system (level 3-4)?

If the answer favors the former → consider M1; if the answer favors the latter → consider M2.

Band 1 Trends in subject selection among secondary school students

Since M1/M2 was recognized as a complete elective subject by universities, most Band 1 secondary schools in Hong Kong have offered M1/M2 courses, and students can choose according to their interests and abilities.

Current subject selection trends

M2 has more students: Since M2 is easier to pass Level 5, and the demand for further studies in science and engineering is high, most students with strong maths abilities will choose M2
Some schools set performance thresholds: Some schools will organize classes based on Form 3 scores. For example, students with the top 30% scores can study M2 first.
There are relatively few students taking M1: But for students interested in business and social sciences, M1 may be more suitable
Class schedule: Due to the freeing up of class time after the transfer of general studies to civics, most schools will allocate about 75% of the class time to M1/M2, and some schools need to make up classes on Saturdays.

Tendency to choose subjects in prestigious schools (reference)

school type	M1/M2 opening status	Subject selection tendency
Traditional prestigious schools (DBS, DGS, La Salle, etc.)	Available in both M1 and M2	M2 for science majors, M1 for business majors
Band 1A secondary school	Most opened M2, and some opened M1 at the same time.	M2 is the mainstream choice
Band 1B/1C secondary school	Depends on school resources	M1 relatively more

Experience sharing from people who have been there

The following is the real-life experience sharing of several DSE candidates to help you understand better M1 M2 respectively Same as actual learning experience:

Experience 1: M2 candidates (engineering direction)

"My Form 3 Core Maths score was about 20% of the whole grade, so I chose M2. I found it difficult at first, especially mathematical induction and matrices, but after getting used to it, I found that the question pattern of M2 is relatively fixed, and it is not difficult to score 5 after mastering Past Paper. In the end, I scored 5* in DSE, and studied engineering at HKUST. If you have a good foundation in mathematics and want to study science and engineering, M2 Definitely worth picking up.”
— 2024 DSE candidate, currently studying at HKUST School of Engineering

Experience two: M1 candidates (business direction)

"I want to study business, and I chose M1 because I think statistics is useful for business. The difficulty of M1 is not in counting, but in understanding the questions and interpreting the answers. Some of the questions are very long, so you have to be careful before you read them wrong. I finally settled on level 4. Although it is not a high score, it has met the admission requirements of most business majors."
— 2024 DSE candidate, currently studying at CUHK Business School

Experience Three: Candidates Converting from M1 to M2

"I chose M1 for Form 4, but I found that I was not suitable for the statistical way of thinking, and I kept losing points on text questions. For Form 5, I switched to M2. Although it was hard to keep up with the progress, I found that the questions in M2 were more direct to me. In the end, I got a level 5 in DSE. I suggest everyone to think clearly about their strengths before choosing a subject."

Course selection tips summarized by experienced people

It's better to just watch "Bian Ke Yi": You need to find out which side science suits your own way of thinking.
Think clearly about the direction of further studies: Choosing a subject will be easier if you have a clear goal
The first semester of Form 4 is the golden observation period: If you find that you are not suitable, transfer to another department as soon as possible
If you choose, stick to it: Both subjects require time to immerse yourself in. It would be a waste to give up midway.

FAQ: Frequently Asked Questions about M1 M2 Subject Selection

Is M1 fixed to M2 easy to get 5**?

According to historical data, the Level 5 cut-off of M2 is relatively low (about 65%), while M1 requires about 80% to reach Level 5 first. However, the M2 course content is deeper and requires more time to understand. In summary, M2 is easier to get high scores, but the prerequisite is that you can master the course content.

My Core Maths scores are average, should I choose M1 or M2?

It is recommended to choose M1. Level 2-4 of M1 has a lower threshold and the content is relatively easy to understand, making it suitable for students with moderate mathematical ability as a stable elective subject. If Core Maths has not reached Level 4, it will be more difficult to choose M2.

I chose the wrong subject in Form 4, can I transfer it?

Yes, but it is recommended to transfer as early as possible. The best time to transfer is before the end of the last semester of Form 4. Transferring too late will make you need to catch up a lot of progress. Some schools also have restrictions on transferring subjects, so it is recommended to check with the school first.

Will not choosing M1/M2 affect my further studies?

It depends on your education goals. If your target major is engineering, science, actuarial science, etc., not taking M1/M2 will be a significant disadvantage. However, if your goals are liberal arts, law, and some social sciences, the impact of not taking extended mathematics will be smaller.

Can I study M1 and M2 at the same time?

In theory, it is possible, but most schools will not open at the same time, and it is difficult to balance the time. It is generally recommended to focus on studying the Form 1 subjects to achieve the best results.

M1 determines M2 There is no absolute answer. The key is to understand your own abilities, interests and study goals. If you are still undecided, please contact Math Insight.
