STPM Tuition Online: Mathematics (T), Physics, Chemistry, Biology, Ekonomi and Pengajian Am
Semester 1 to 3 classes for Form 6 students, in Bahasa Melayu or English, planned around each semester's paper.
Founder & Head of School, Afterkelas
Afterkelas teaches STPM online to Form 6 students across the three semesters that Majlis Peperiksaan Malaysia examines. University tutors run live classes in Mathematics, the sciences, the commerce subjects and Pengajian Am, 1-to-1 or in small groups, in Bahasa Melayu or English.
Subjects we teach for STPM
Mathematics (T) and the three sciences are the core of our STPM work, with Mathematics (M), the commerce subjects and Pengajian Am alongside. Each subject below has its own page with the topics of every semester and a worked question; the rest of this page applies to all of them.
STPM Mathematics (T), now named Mathematics 954: algebra and geometry, calculus, then statistics, with one written paper each semester.
STPM Mathematics (M), now named Management Mathematics 950: algebra and calculus, statistics, then financial and decision mathematics.
STPM Physics across 26 topics and three semesters, from kinematics to nuclear physics, with the practical work that makes up a fifth of the grade.
STPM Chemistry by semester: general and inorganic chemistry, physical chemistry, then organic chemistry, with practical work worth a fifth of the grade.
STPM Biology by semester: molecules of life and metabolism, physiology, then biodiversity, ecology and genetics, with practical work worth a fifth of the grade.
STPM Ekonomi by semester: Mikroekonomi, Makroekonomi, then Ekonomi Gunaan, with the diagrams, calculations and essays each paper marks.
STPM Pengajian Perniagaan by semester: business and management, the business functions, then communication, entrepreneurship and ethics, with a case study in every paper.
STPM Perakaunan by semester: financial accounting in Semesters 1 and 2, management accounting in Semester 3, and the computerised accounting coursework.
STPM Pengajian Am, the subject public universities require: Malaysian nationhood, the research project, turning data into text, and essays in Bahasa Melayu.
How the semester system changes revision
STPM is examined in three stages. Each subject has one paper per semester, sat at the end of that semester, and the three results combine into the final grade. A weak Semester 1 or Semester 2 paper can be retaken once, but only at the end of Semester 3, on top of that semester's own papers, and the better of the two scores counts.
That makes the first semester the one to protect. Form 6 students arrive from SPM expecting a slow start and find a paper waiting for them within months. A retake is possible, but it lands in the final exam season beside the Semester 3 papers, so a good first attempt saves a crowded finish.
Each semester therefore runs as its own short course. The tutor covers the semester's topics alongside the college, then turns to past papers and timing before the semester examination, and starts the next semester's topics only once the paper is sat. In Mathematics (T), for example, each semester's paper covers its own set of topics, and a student who leaves revision to the final month of Form 6 is partly revising for papers already sat.
Coursework, and what tuition can and cannot do
Several STPM subjects include school-based assessment done under the teacher's supervision: 15 experiments across the three semesters in Physics, Chemistry and Biology and computerised accounting work in Perakaunan, each worth 20 percent, and a research project with a presentation in Pengajian Am. Under the syllabuses examined from November 2025, the mathematics papers, Ekonomi and Pengajian Perniagaan have no coursework. Coursework is assessed as the student's own work, and it cannot be retaken.
A tutor can explain the science, accounting or research method the work depends on, check that the student understands their own method, and help them read the marking criteria. A tutor will not write any part of it. Coursework that is not the student's own is a risk to the whole result, and the understanding it builds is the point of it anyway.
Bahasa Melayu or English
The mathematics and science papers, Mathematics (T) and (M), Physics, Chemistry and Biology, are printed in both Bahasa Melayu and English, and answers may be written in either. Classes follow the language the student will answer in, and tutors use the terms from that version of the paper, so nothing needs translating in the examination hall.
Ekonomi, Pengajian Perniagaan, Perakaunan and Pengajian Am are examined in Bahasa Melayu only. Tutors can explain an idea in English when that helps, and answers are always practised in the Malay terms the paper uses.
Grades and the CGPA universities read
Each STPM subject is graded from A to F, with grade points from 4.00 for an A down to 0.00. The overall CGPA averages the four best subjects, and Pengajian Am is one of them for anyone applying to a public university, where it is required alongside at least three other subjects.
Because the CGPA is an average, one weak subject pulls on everything else. When a student is strong in three subjects and struggling in the fourth, tuition in the weak subject usually does more for the CGPA than extra hours in the strong ones.
A question, worked through
A Semester 1 Mathematics (T) question on complex numbers. It is short, and it rewards the student who understands why multiplying by the conjugate works.
Question
Express (3 + 4i)/(1 − 2i) in the form a + bi. Hence find its modulus and its argument, giving the argument in radians to three decimal places.
- Multiply the numerator and the denominator by the conjugate of the denominator, 1 + 2i. The denominator becomes (1 − 2i)(1 + 2i) = 1 + 4 = 5, a real number, which is the whole purpose of the step.
- Expand the numerator: (3 + 4i)(1 + 2i) = 3 + 6i + 4i + 8i² = 3 + 10i − 8 = −5 + 10i.
- Divide by 5: (−5 + 10i)/5 = −1 + 2i.
- The modulus is √((−1)² + 2²) = √5.
- For the argument, draw the point (−1, 2) first: it lies in the second quadrant, so the argument is π − tan⁻¹(2) = 3.1416 − 1.1071 = 2.034 radians. A calculator given tan⁻¹(2 ÷ −1) returns −1.107, which is in the wrong quadrant.
Answer −1 + 2i, with modulus √5 and argument 2.034 radians.
Frequently asked questions
Are STPM classes taught in Bahasa Melayu?
Yes, or in English. The mathematics and science papers are set in both languages, and classes follow the one the student will answer in. Ekonomi, Pengajian Perniagaan, Perakaunan and Pengajian Am are examined in Bahasa Melayu, so answers are practised in Malay even when an idea is first explained in English.
Do you help with the coursework component?
With understanding it, yes: the tutor explains the concepts the project rests on and goes through the marking criteria with the student. A tutor does not write coursework or any part of it: it is assessed as the student's own work under the school's supervision.
When should STPM tuition start?
At the start of Semester 1. Each semester's paper is sat at the end of that semester, and while a Semester 1 or 2 paper can be retaken once, the retake comes at the end of Semester 3 alongside that semester's papers. Starting later still helps with the papers that remain and with any retake.
How much does STPM tuition cost?
It depends on the format, the number of subjects and how often classes run, so there is no single figure. Tell an academic advisor the subjects, the semester and the latest results, and you will get the current packages and a quote on WhatsApp, usually within one working day.
How do universities read the STPM result?
Each subject earns a grade with a grade point, from 4.00 for an A down to 0.00 for an F, and the CGPA averages the four best subjects including Pengajian Am. Public universities require Pengajian Am and at least three other subjects, so a weak subject costs more than its own grade suggests.
Can one subject be taken 1-to-1 and another in a group?
Yes. A common arrangement is private classes for the subject pulling the CGPA down and a small group for a subject that needs steady practice. The advisor suggests a mix once they have seen the latest semester results.
