What is TU Grading System?

Tribhuvan University (TU), Nepal's oldest and largest university, uses a 4.0-point Grade Point Average (GPA) scale for semester-based programs. The grading system was introduced to standardize academic performance evaluation and transition away from percentage-based divisions.

📌 Key Fact: TU has TWO different systems:

  • Semester System (Modern): Uses 4.0 GPA scale with letter grades (A, A-, B+, etc.) — used in BCA, BBS, BIM, Engineering, and newer programs
  • Annual System (Legacy): Uses percentage divisions (Distinction, First Division, Second Division, Pass) — still used in some older programs

Established: TU began transitioning to semester system from 2074/75 (2017/18). Most new student admissions now use semester-based grading.

Applies to: BCA, BBS, BBM, BIM, Engineering (all streams), Medicine, Agriculture, Law, Humanities — basically all TU programs under semester system.

TU Grading System 2082 for Bachelors & Masters

The current TU grading system (as of 2082/2026) uses a 4.0-point scale with letter grades. Your percentage marks are converted to letter grades, which are then converted to grade points.

Grade Scale with Conversion Table

Below is the official TU grading scale showing percentage ranges, letter grades, grade points, and descriptions:

Percentage Range (%) Letter Grade Grade Point Description Class / Division
90–100 A 4.0 Outstanding / Excellent Distinction
80–89 A- 3.7 Very Good Distinction / First Division
70–79 B+ 3.3 Good / First Division First Division
60–69 B 3.0 Satisfactory First Division / Second Division
55–59 B- 2.7 Acceptable / Passing Second Division
50–54 C+ 2.3 Passing (Lower) Second Division
45–49 C 2.0 Minimum Pass Pass / Third Division
40–44 D 1.7 Conditional Pass Pass / Third Division
Below 40 F 0.0 Fail (No Credit) FAIL

Note: These grade conversions apply to TU semester system (BCA, BBS, Engineering, Medicine, etc.). Annual system programs may use slightly different ranges. Always verify with your department.

How to Convert TU Percentage to GPA

Understanding the conversion process helps you calculate your own GPA. Here's a step-by-step breakdown:

The Conversion Method

TU percentage to GPA conversion is straightforward:

GPA = Percentage ÷ 25 (approximate)

But use the official table above for exact conversion

Worked Examples

Example 1: Student scores 82% in a subject

  • Percentage: 82%
  • Falls in range: 80–89%
  • Corresponding Grade: A-
  • Grade Point: 3.7
  • Result: 82% = A- (3.7 GPA)

Example 2: Student scores 72% in Mathematics

  • Percentage: 72%
  • Falls in range: 70–79%
  • Corresponding Grade: B+
  • Grade Point: 3.3
  • Result: 72% = B+ (3.3 GPA)

Example 3: Student scores 45% (Just passing)

  • Percentage: 45%
  • Falls in range: 45–49%
  • Corresponding Grade: C
  • Grade Point: 2.0
  • Result: 45% = C (2.0 GPA) — Minimum to pass

Important TU Grading Rules & Requirements to Remember

Beyond the grade scale, TU has specific policies that affect your academic standing and graduation prospects.

Passing Requirements

  • Individual Subject Pass: Minimum 40% (Grade D or above) to pass a course and earn credit
  • Semester Pass: Minimum semester GPA of 2.0 required to pass the semester (varies by program)
  • Graduation Requirement: Minimum CGPA (cumulative GPA) of 2.0 required to graduate (varies by program)
  • No Partial Credit: If you fail (F grade), you get 0.0 grade points and must retake the course

Class/Division Awards

  • Distinction: CGPA 3.6–4.0 — Highest honor, appears on diploma
  • First Division: CGPA 3.0–3.59 — Upper tier honor
  • Second Division: CGPA 2.0–2.99 — Average pass
  • Below 2.0: May not graduate or face probation (depends on program)

Make-up & Retake Policy

  • Retake Allowed: You can retake any course to improve your grade
  • Grade Replacement: When you retake a course, only the higher grade counts toward CGPA
  • Both Attempts Recorded: Both grades appear on transcript, but higher one affects GPA
  • Make-up Exams: Available for special circumstances (illness, emergency); contact your department

Credit Hours Impact on GPA

  • Weighted Average: GPA = Total (Grade Points × Credit Hours) ÷ Total Credit Hours
  • Higher Credit = More Impact: A 4-credit course with Grade A affects GPA more than 2-credit course with Grade A
  • Focus on High-Credit Courses: Prioritize studying for courses with 4+ credits to maximize GPA
  • Semester Credits Vary: Most semesters have 15–21 credits total

Theory vs Practical Marks

  • Theory Marks: From written exams (typically 70–80% of grade)
  • Practical Marks: From lab work, projects, presentations, viva (20–30% of grade)
  • Combined Grade: Both are converted to the same grading scale and combined for final grade
  • Some Subjects: May have only theory (no practical component)
  • Minimum in Both: You typically need minimum grade in both theory and practical to pass

TU Grading System for Different Programs

While the 4.0 GPA scale is standard, some programs have slight variations. Here's what to expect:

Engineering Programs (BEx)

Uses: 4.0 GPA scale (same as above)

Typical Semester Load: 18–21 credits

Passing GPA: Minimum 2.0 per semester, 2.0 CGPA for graduation

Distinction: 3.6+ CGPA

BCS/BCA (Computer Science)

Uses: 4.0 GPA scale

Typical Semester Load: 16–18 credits

Passing GPA: Minimum 2.0 per semester

Distinction: 3.6+ CGPA

BBS/BBM (Business)

Uses: 4.0 GPA scale

Typical Semester Load: 15–18 credits

Passing GPA: Minimum 2.0

Distinction: 3.6+ CGPA

Medicine/Health Sciences

Uses: 4.0 GPA scale (may have higher pass requirements)

Typical Semester Load: 16–20 credits

Passing GPA: Minimum 2.0–2.5 (stricter than other programs)

Distinction: 3.6+ CGPA

Always check with your department for program-specific requirements, as they can vary slightly year to year.

Frequently Asked Questions About TU Grading System

How does TU convert percentage to GPA?
TU uses different conversion methods: For semester systems (BCA, BBS, etc.): Grade A (90–100%) = 4.0, A- (80–89) = 3.7, B+ (70–79) = 3.3, B (60–69) = 3.0, B- (55–59) = 2.7, C+ (50–54) = 2.3, C (45–49) = 2.0, D (40–44) = 1.7, F (<40) = 0.0. For annual systems: Percentage/25 ≈ GPA (approximate).
What is the minimum GPA to pass at TU?
Minimum passing GPA at TU is typically 1.7 (Grade D, around 40%). However, some programs require a minimum semester GPA of 2.0, and graduation usually requires CGPA 2.0. Always check your program-specific requirements.
What GPA do I need for Distinction at TU?
Distinction at TU typically requires CGPA 3.6 or above at graduation. Some programs may have slightly different thresholds (3.5-3.7). Check with your department.
Does TU have different grading systems for different programs?
Yes. Older programs use annual system with percentage divisions (Distinction 75%+, First Division 60-74%, etc.). Newer programs (BCA, BBS, Engineering) use semester system with 4.0 GPA scale. The conversion tables in this guide apply to semester-based programs.
What are "theory" and "practical" marks in TU grading?
Theory marks are from written exams (typically worth 70-80% of final grade). Practical marks are from lab work, projects, or viva (20-30%). Some subjects have only theory. Both are converted to the same grading scale and combined for final grade.
Can I retake a course to improve my grade at TU?
Yes, TU allows students to retake courses. Grade replacement policy states that when you retake a course, the higher grade is counted toward CGPA, not the lower one. This helps improve your cumulative GPA.
What happens if I fail a subject at TU?
If you score below 40% (F grade), you fail the course and get 0.0 grade points. You must retake the course. The retake grade replaces the fail in your CGPA calculation. Failing too many courses can impact your academic standing.
Is TU GPA 2.0 considered good?
TU GPA 2.0 (Grade C) meets minimum graduation requirement, but is not competitive. For scholarships, grad school, and jobs, aim for 2.5+. GPA 3.0+ is considered good and competitive. GPA 3.5+ is excellent.
