To calculate the pointer for the Sijil Tinggi Persekolahan Malaysia (STPM), you need to understand the two main components: Nilai Gred Mata Pelajaran (NGMP) and Purata Nilai Gred Kumulatif (PNGK). Here’s a step-by-step guide:
Step-by-Step Calculation
1. Understanding NGMP
NGMP is derived from your grades in each subject across different semesters and any coursework. Each subject has a specific weightage for its components, typically distributed as follows:
- Semester 1: 29%
- Semester 2: 22%
- Semester 3: 29%
- Coursework: 20%
2. Assigning Grades to NGMP
Each grade corresponds to a specific point value:
| Grade | Point |
|---|---|
| A | 4.00 |
| A- | 3.67 |
| B+ | 3.33 |
| B | 3.00 |
| B- | 2.67 |
| C+ | 2.33 |
| C | 2.00 |
| C- | 1.67 |
| D+ | 1.33 |
| D | 1.00 |
| F | 0.00 |
3. Calculating NGMP for Each Subject
For each subject, multiply the grade points by their respective weightages and sum them up.
Example Calculation for a Subject: Assume the following grades:
- Pengajian Am:
- Semester 1: A- (3.67)
- Semester 2: B (3.00)
- Semester 3: A (4.00)
- Coursework: A (4.00)
The calculation would be:
NGMP = (0.29 × 3.67) + (0.22 × 3.00) + (0.29 × 4.00) + (0.20 × 4.00)
Calculating this gives:
NGMP = (1.0643) + (0.66) + (1.16) + (0.8) = 3.6843 (rounded to 3.68)
4. Calculating PNGK
The PNGK is calculated by averaging the NGMP of your best four subjects:
PNGK = (Sum of best four NGMP) / 4
Example Calculation for PNGK: If your best four subjects have NGMPs of:
- Subject A: 3.68
- Subject B: 3.67
- Subject C: 3.33
- Subject D: 3.67
Therefore,
PNGK = (3.68 + 3.67 + 3.33 + 3.67) / 4 = 14.35 / 4 = 3.5875 ≈ 3.59
Important Notes
- Ensure that you only include grades from subjects where you have achieved passing marks.
- The final PNGK will determine your eligibility for university admissions.
This method provides a clear framework for calculating your STPM pointer, allowing students to estimate their results effectively based on their performance in each semester and coursework.
