INRS (Institut national de la recherche scientifique) uses a 4.3 letter-grade scale where an A+ is worth 4.30 grade points, making it one of the Canadian universities that rewards exceptional performance beyond the standard 4.0 maximum. This Quebec-based research institute employs a detailed grading structure with 14 distinct letter grades ranging from A+ (90–100%, 4.30 GPA) down to F (0–49%, 0.00 GPA). Unlike many universities that cap their scales at 4.0, INRS recognizes top-tier achievement with the 4.30 value for grades of 90% or above. The system includes plus and minus modifiers for A, B, C, and D grades, allowing for nuanced assessment of student performance across the full percentage spectrum. Students must achieve at least 50% (D-, 0.70 GPA) to pass a course.

Frequently Asked Questions — INRS

What GPA scale does INRS use?
INRS uses a 4.3 letter-grade scale where the highest achievable GPA is 4.30 for an A+ (90–100%). This scale includes 14 distinct letter grades from A+ down to F, with plus and minus modifiers for most grade categories. The 4.3 maximum distinguishes INRS from institutions using the more common 4.0 scale cap.
How is GPA calculated at INRS?
GPA at INRS is calculated by converting each percentage grade to its corresponding letter grade and grade point value, then computing the weighted average based on course credits. For example, 92% converts to A+ (4.30 points), 82% converts to A- (3.70 points), and 75% converts to B (3.00 points). Each course's grade points are multiplied by its credit hours, summed, and divided by total credits attempted.
What letter grade is 80% at INRS?
A score of 80% at INRS corresponds to an A- letter grade, which is worth 3.70 grade points. The A- grade range spans 80–84%, falling within the Outstanding performance category. This sits just below the A grade range of 85–89% (4.00 points) and well above the B+ range of 77–79% (3.30 points).
What is a 3.7 GPA at INRS?
A 3.70 GPA at INRS is equivalent to an A- letter grade, representing Outstanding performance in the 80–84% range. This GPA places a student well above the Very good category (B grades, 2.70–3.30) and just below the A grade threshold of 4.00. Maintaining a 3.70 GPA demonstrates consistently strong academic achievement.
What is considered a good GPA at INRS?
At INRS, a GPA of 3.00 or higher is generally considered good, as this corresponds to B-range performance classified as Very good. A GPA of 3.70 or above (A- or better) is considered excellent and places students in the Outstanding category. For competitive graduate programs or scholarships, aiming for 3.70 or higher is typically advisable.
How do I convert INRS percentages to GPA?
To convert INRS percentages to GPA, match your percentage to the corresponding letter grade range, then use the assigned grade point value. For instance, 90–100% equals A+ (4.30), 85–89% equals A (4.00), 80–84% equals A- (3.70), and so on through the scale down to 0–49% for F (0.00). Each letter grade has a fixed GPA value regardless of where you fall within its percentage range.
What is the passing grade at INRS?
The minimum passing grade at INRS is 50%, which corresponds to a D- letter grade worth 0.70 grade points. Any percentage below 50% results in an F (0.00 GPA) and constitutes a failure. Students must achieve at least this threshold to receive credit for a course.
Where can I find INRS's official grading policy?
INRS's official grading information can be found through the Registrar's Office section of their website at https://inrs.ca/en/studies/registrars-office/. The Registrar's Office provides comprehensive academic regulations including detailed grading scales, GPA calculation methods, and academic standing requirements. Students should consult this official source for the most current and complete grading policies.
