Formula Used
The Master Stream Ontario score is calculated using the following formula:
Master Stream Score Formula
Master Stream Score = (English × 0.15) + (Mathematics × 0.15) + (Science × 0.15) + (Additional Course 1 × 0.1) + (Additional Course 2 × 0.1) + (Additional Course 3 × 0.1) + (Additional Course 4 × 0.1)
Where each course score is based on your Ontario high school mark converted to a percentage.
This formula gives equal weight to each of your six required courses, with slightly higher emphasis on English, Mathematics, and Science.
Worked Example
Let's calculate a sample Master Stream score:
| Course | Mark (%) | Weight | Contribution |
|---|---|---|---|
| English | 85 | 15% | 12.75 |
| Mathematics | 90 | 15% | 13.50 |
| Science | 88 | 15% | 13.20 |
| Additional Course 1 | 82 | 10% | 8.20 |
| Additional Course 2 | 78 | 10% | 7.80 |
| Additional Course 3 | 80 | 10% | 8.00 |
| Additional Course 4 | 75 | 10% | 7.50 |
| Total Score | 65.95 | ||
In this example, the student's Master Stream score is 65.95, which would be rounded to 66 for admission purposes.
Interpreting Your Results
Your Master Stream score is an important factor in university admissions. Here's what the different score ranges typically mean:
- 60-69: Competitive for many programs, especially in less competitive universities.
- 70-79: Strong competitive score for most programs.
- 80-89: Very competitive score, especially for top universities.
- 90+: Extremely competitive score, likely to be accepted to most universities.
