What Is TU BSc General?
TU BSc General is structured as a multi-subject science degree in which the number of core subjects decreases as students move through the program.
The revised curriculum starts with three core subjects. Students continue the same three subjects in the second year, select two of them for the third year, and retain one of those subjects as the fourth-year major. Supporting courses are placed alongside the core subjects throughout the program.
This progression is one of the defining features of the General B.Sc. structure. The fourth-year major is not introduced as an unrelated new discipline; it develops from a subject already studied during the third year.
How the Four-Year Curriculum Is Structured
The four-year structure combines core science study with compulsory, elective, research-related, computational, and interdisciplinary components. Each year carries 500 marks under the revised course framework.
| Year | Main academic structure | Marks |
|---|---|---|
| First Year | 3 core subjects + Scientific Communication | 500 |
| Second Year | Same 3 core subjects + Applied Statistics | 500 |
| Third Year | 2 core subjects + Research Methodology + 2 electives | 500 |
| Fourth Year | 1 major subject + project/field work or Applied Science + Computational Course + Interdisciplinary Course | 500 |
| Total | Four-year B.Sc. structure | 2,000 |
First-Year BSc General Structure
The first year consists of three core subjects selected from either the Physical or Biological group, together with compulsory Scientific Communication.
Each core subject carries:
-
Theory: 100 marks
-
Practical: 50 marks
Three core subjects therefore account for 450 marks.
Scientific Communication carries another 50 marks, bringing the first-year total to 500 marks.
The curriculum describes Scientific Communication as a compulsory paper rather than a core science subject.
Second-Year BSc General Structure
The second year continues the same three core subjects studied in the first year.
The marks remain:
-
Theory: 100 marks for each core subject
-
Practical: 50 marks for each core subject
-
Three core subjects: 450 marks
Applied Statistics is added as a 50-mark theory paper. The second-year total is therefore 500 marks.
Continuing the same three subjects preserves the subject sequence established in the first year before students reduce their core selection in the third year.
Third-Year BSc General Structure
The third year reduces the core science load from three subjects to two.
Students continue any two subjects from their first- and second-year core study. Each carries 100 marks for theory and 50 marks for practical work, producing 300 marks across the two core subjects.
The remaining third-year components are:
-
Research Methodology: 100 marks
-
Two elective courses from the respective subject pool: 50 marks each
The two electives contribute 100 marks, giving the third year a total of 500 marks.
Fourth-Year BSc General Structure
The fourth year concentrates the core component into one major subject selected from the student's third-year study.
The major component consists of two courses from the same subject. The curriculum allocates:
-
Two theory courses: 100 marks each
-
Practical components: 50 marks each
-
Major/core component total: 300 marks
The remaining 200 marks come from three curriculum areas:
-
Project Work/Field Work or Applied Science: 100 marks
-
Computational Course: 50 marks
-
Interdisciplinary Course: 50 marks
The Computational Course is identified as a compulsory paper and includes theory/laboratory work. The Interdisciplinary Course is a theory paper.
TU's third- and fourth-year syllabus also contains subject-level courses, including fourth-year project work and interdisciplinary study within individual disciplines.
Marks Distribution in TU BSc General
The revised four-year structure assigns an equal 500 marks to each year.
| Academic year | Marks |
|---|---|
| First Year | 500 |
| Second Year | 500 |
| Third Year | 500 |
| Fourth Year | 500 |
| Total | 2,000 |
The distribution combines theory, practical work, compulsory supporting papers, electives, research-related study, and fourth-year interdisciplinary and computational components.
Subjects Listed in the Revised Curriculum
The first-year revised syllabus lists ten science disciplines alongside compulsory Scientific Communication.
The science subjects listed are:
-
Botany
-
Chemistry
-
Environmental Science
-
Geology
-
Mathematics
-
Meteorology
-
Microbiology
-
Physics
-
Statistics
-
Zoology
Scientific Communication appears separately as the compulsory first-year paper.
The revised third-year syllabus lists the same ten science disciplines and Research Methodology. The third year requires students to continue two core subjects from their earlier study while also completing Research Methodology and two electives from the relevant subject pool.
The fourth-year major comes from a core subject retained in the third year.
Physical and Biological Group Structure
The revised curriculum organizes first-year core subject selection through Physical and Biological groups.
Its four-year structure specifies that students take any three core subjects from either the Physical or Biological group in the first year. The same three subjects continue in the second year. Two are retained in the third year, and one of the third-year subjects becomes the fourth-year major.
The central structure table establishes the group-based progression but does not assign every listed science discipline to a group within that table. For that reason, the program structure is stated here without creating an unsupported Physical-versus-Biological subject allocation.
Compulsory and Supporting Courses
TU BSc General includes supporting courses at each stage of the four-year program rather than consisting only of core science papers.
Scientific Communication
Scientific Communication is a compulsory 50-mark theory paper in the first year.
It sits alongside the three core science subjects and completes the 500-mark first-year structure.
Applied Statistics
Applied Statistics is a 50-mark theory paper in the second year.
The three continuing core subjects account for 450 marks, while Applied Statistics brings the second-year total to 500 marks.
Research Methodology
Research Methodology carries 100 marks in the third year.
It is studied alongside two continuing core subjects and two elective courses.
Elective Courses
Third-year students take two elective courses from the respective subject pool.
Each elective carries 50 marks, giving a combined elective value of 100 marks.
Project Work, Field Work, or Applied Science
The fourth year assigns 100 marks to Project Work/Field Work or Applied Science leading to the student's core subject.
The structure identifies research work and presentation in connection with the project/field-work route. Subject-level syllabi provide additional detail for individual disciplines.
Computational Course
The fourth year includes a compulsory Computational Course carrying 50 marks.
The curriculum classifies it as a theory/laboratory paper.
Interdisciplinary Course
Students also take one 50-mark Interdisciplinary Course in the fourth year.
It forms the final 50 marks of the 500-mark fourth-year structure.
How the Major Subject Develops
The major subject is selected through a sequence that begins in the first year.
The curriculum progression is:
-
First Year: three core subjects
-
Second Year: the same three core subjects
-
Third Year: two subjects retained from the earlier years
-
Fourth Year: one subject retained from the third year as the major
The fourth-year major carries 300 marks through two theory courses and practical components. The remaining 200 marks come from project/field work or Applied Science, the compulsory Computational Course, and one Interdisciplinary Course.
This structure links the fourth-year major directly to the student's earlier core study rather than treating the major as a separate subject chosen only in the final year.
Conclusion
Tribhuvan University's General B.Sc. is a four-year annual-system science degree administered through the Institute of Science and Technology. Its revised 2073 structure carries 2,000 marks, divided equally across four academic years.
The curriculum begins with three core subjects, retains the same three in the second year, reduces them to two in the third year, and concentrates on one major subject in the fourth year. Scientific Communication, Applied Statistics, Research Methodology, electives, project or field work or Applied Science, a Computational Course, and an Interdisciplinary Course form the supporting academic structure around that progression.
