Report-Grade Weight in SNBP
In Seleksi Nasional Berdasarkan Prestasi (SNBP), report grades are the main component. The SNPMB committee sets a minimum weight of 50 percent for the average report grades of all subjects, while up to 50 percent comes from the interest-and-talent component — such as achievements or supporting subjects relevant to the chosen study program.
Grades assessed cover report cards from semester 1 through semester 5. Semester 6 (the final semester of grade 12) is excluded because selection runs before that semester ends. Keeping grades up from grade 10 is therefore as important as grades in grade 12.
Formula for Average Report Grades
The basic formula is simple: add up all subject grades from semesters 1 to 5, then divide by the total number of grade data points. If each semester has the same number of subjects, the data count equals subjects multiplied by five semesters.
Example: a student has 6,437 total grade points from 75 data points over five semesters (15 subjects x 5 semesters). The average is 6,437 divided by 75, which is 85.82. For a per-semester average: total grades in one semester divided by that semester's subject count — e.g., 1,000 divided by 12 subjects equals 83.3.
Supporting Subjects and Achievements
Beyond the all-subject average, PTN may assess up to two supporting subjects relevant to the chosen program. For instance, engineering applicants benefit from high mathematics and physics grades. A simulated final score can be computed as: (component-1 weight x all-subject average) + (component-2 weight x supporting-subject average).
Academic and non-academic achievements can add value but are not mandatory. Surveys show about 60 percent of students admitted via SNBP submitted no achievement certificates — meaning consistent report grades remain the main determinant of admission.
Tips for Calculating and Improving Your Chances
Use all subjects in your calculation, not just favorites, so the simulation resembles official assessment. Keep the grading scale uniform (usually 0-100) and match it with PDSS data — report-data mismatches can disrupt registration.
Equally important is the grade trend. Consistently rising grades across semesters are valued more than high but wildly fluctuating grades. Remember, a self-simulation is not the final SNBP score since each PTN may use different weight compositions. Use the calculation to plan a realistic program-choice strategy.
