Environmental Science Honours CGPA Calculator

NU CGPA (Cumulative Grade Point Average) measures overall academic performance across all years of your program. Each subject earns a grade point (0.00–4.00) which is multiplied by its credit hours. The CGPA is the sum of all weighted grade points divided by the total credit hours (128 for Honours, 84 for BA Program, 24 for Degree Pass).

National University Bangladesh uses a 4.00 grading scale: A+ (80–100%) = 4.00, A (75–79%) = 3.75, A- (70–74%) = 3.50, B+ (65–69%) = 3.25, B (60–64%) = 3.00, B- (55–59%) = 2.75, C+ (50–54%) = 2.50, C (45–49%) = 2.25, D (40–44%) = 2.00, F (below 40%) = 0.00.

The 4-year Honours program requires 128 total credits (28 + 28 + 32 + 40). The 3-year BA Program requires 84 credits. The 3-year Degree Pass requires 24 credits. Each department may have slight variations — use the calculator to see the exact distribution for your department.

No. English (Second Year) is a non-credit compulsory subject. It does not count toward total credits or CGPA, but you must pass it to complete the program. The calculator marks non-CGPA subjects clearly and includes them only in the passed-subject count.

A failed subject (F, below 40%) earns 0.00 grade points. Its credit hours still count in total credits, which lowers your GPA. Improvement rules depend on current National University regulations; consult the latest official examination notices for retake and transcript policies.

Classification is determined by final CGPA: First Class (3.00–4.00), Second Class (2.25–2.99), Third Class (2.00–2.24). A CGPA below 2.00 does not meet the minimum requirement for graduation. This applies to all programs (Honours, BA Program, and Degree Pass).

Some departments require choosing optional subject groups. For example, Zoology First Year chooses one group (Chemistry or Biochemistry) and Second Year chooses any two. Physics First and Second Years choose one group (Chemistry or Statistics). The calculator prompts you to select before showing the subject list.

Yes. Enter actual grades for completed years and estimated grades for remaining years. The calculator will project your final CGPA and show what classification you would achieve.

It follows the official NU grading scale and weighted credit formula: Σ(Grade Point × Credit) / Σ(Credit). Verify with your college for any institution-specific variations.

Yes. Higher-credit subjects have a greater impact on CGPA. A 4-credit theory subject counts twice as much as a 2-credit practical. The calculator applies the correct weighted averaging.

Select your program and department, choose the academic year, pick optional groups if applicable, enter your grades for each subject, and click Calculate. Check "Overall CGPA" to calculate across all years at once.

The program covers environmental chemistry, ecology and biodiversity, earth sciences, meteorology and climate, remote sensing and GIS, environmental toxicology, disaster management, water resources, waste management, environmental law and policy, and sustainable development. Fieldwork and laboratory work are integral components.

Yes, students complete Laboratory and Fieldwork papers each year. First year includes a dedicated fieldwork paper worth 4 credits, second year continues with laboratory and fieldwork, and third and fourth years include advanced fieldwork and research methodology components.

Graduates can work in environmental consulting firms, government agencies (DoE, BWDB, DPHE), NGOs, disaster management organisations, renewable energy sectors, environmental research institutes, and international development organisations focusing on climate change and sustainability.
