About Botany Honours CGPA Calculation

The National University Botany Honours program provides a deep understanding of plant sciences, from microorganisms to higher plants. Over four years, students study microbiology, mycology, phycology, plant physiology, plant biochemistry, ecology, genetics, molecular biology, biotechnology, and economic botany. The curriculum is designed to build foundational knowledge in the first two years and advanced specialisation in the third and fourth years, including practical laboratory work each year. Using the official NU grading system, Honours students can calculate their semester GPA and overall CGPA to monitor academic progress toward First Class, Second Class or other degree classifications. This CGPA calculator is built specifically for Botany students following the NU syllabus.

How This Botany CGPA Calculator Works

The calculator converts each selected letter grade into the official NU grade point, multiplies it by the subject credit, and divides the total weighted points by total counted credits.

Botany subjects, optional groups, practical papers, compulsory papers, and non-CGPA subjects are loaded from the department data below so the calculation matches the year-wise structure of the program.

Frequently Asked Questions

NU CGPA (Cumulative Grade Point Average) measures overall academic performance across all years of an Honours 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).
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: First Year 28 credits, Second Year 28 credits, Third Year 32 credits, and Fourth Year 40 credits. Theory subjects carry 4 credits each, practicals carry 2 credits, and the Fourth Year includes a viva-voce (4 credits). Note that some departments may have a different total credit structure (e.g., Botany 136, Economics 120).
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.
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 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 Botany Honours program covers microbiology, mycology, phycology, plant anatomy, taxonomy of angiosperms, plant physiology, plant biochemistry, ecology, plant pathology, cytology, genetics, molecular biology, biotechnology, economic botany, and agronomy. It provides a comprehensive foundation across all major branches of plant science.
Yes, practical papers are included every year: Practical-I in the first year, Practical-II in the second year, Practical-III in the third year, and Practical-Paper IV in the fourth year. Each practical carries 4 credits and 100 marks, emphasising laboratory skills and field-based plant identification.
The Botany Honours program requires a total of 136 credits across four years: 36 credits in the first year, 28 in the second, 32 in the third, and 40 in the fourth year. This includes core subjects, practical work and compulsory courses.
