Degree Programmes

The faculty conducts following degree programms for students.

Principal Subjects

The Faculty conducts Bachelor of Science (B.Sc.) General Degree programmes and B.Sc. Special Degree Programmes in most of the Principal Subjects:

100 Level: following subjects are available at the 100 level;

  • Biology*
  • Biology**
  • Chemistry
  • Computer Science
  • Geology
  • Mathematics
  • Physics
  • Statistics

(At the 100 Level two principal subject areas, Biology* and Biology**, having 8 and 16 credits respectively are offered jointly by the Departments of Botany , Molecular Biology & Biotechnology and Zoology. Both Biological and Physical Science students can offer these subjects.)

200/300/400 Level: subjects available are;

  • Biology
  • Botany
  • Chemistry
  • Computer Science
  • Geology
  • Mathematics
  • Molecular Biology & Biotechnology
  • Physics
  • Statistics
  • Zoology

Initially, a student registers for a General Degree Programme, and at the end of the second year, he/she may continue to follow the general degree programme or register for a special degree programme in a principal subject. The second option is possible only if he/she fulfills certain criteria for selection to a Special Degree Programme. The duration of a general degree programme is normally three years, while that of a special degree programme is four years. General degree students may at the end of 3 rd year be selected based on performance and given the option of following courses for an additional year with special emphasis on industry-related courses leading to a B.Sc. degree in Applied Sciences in place of a General Degree.

The Faculty also conducts four year B.Sc. degree programmes in Computation and Managements (jointly with the Faculty of Arts) and in Statistics and Operations Research for students admitted from a separate window.

Course Units

The Faculty conducts courses under a semester based course unit system. The medium of instruction shall be English. Students can seek the assistance of the academic councellsor and academic advisors who will help him/her to select appropriate subject combinations. Students are responsible for planning their programmes, but they will be guided by the academic councellor and advisors to select course units required for the degree programme.

The course units offered by each department will be available at the beginning of each semester, and the students are required to register using the appropriate form on or before a date specified by the Faculty. Late registrations may be accepted under exceptional circumstances at the discretion of the Faculty on payment of the prescribed fine. In each academic year, a student must register for not less than 27 and not more than 33 credits, excluding course units which are being repeated. Academic advisors will help students to select course units judiciously. Once the course units are selected, the students shall register for each course unit thus selected at the beginning of the semester and he/she can offer only these course units to earn credit.

Subject Combinations

During the first year, students other than those who have been admitted from a separate window shall select three subjects from the principal subject area and select the course units coming under these subjects (subject combinations will be offered are listed end of this section). Students should follow all the components of the selected subjects, i.e. theory, practicals, field work etc. During the second year of the degree programme, students shall select at least two subjects from the principal subject area at 200 level (refer to the “Requirements to Pass the General Degree"). The remaining credits require, if any, shall be selected from the other subjects in the principal subject area/supplementary courses. During the third year of the general degree programme, the students shall select the respective course units at 300 level as in the second year. In case a student selects only two principal subjects, he/she should select at least 6 credits each at 200 and 300 levels from principal subject area/supplementary courses other than course units from the two principal subjects.

General degree students who at the end of 300 level are selected to the fourth year of the programme leading to the B.Sc. degree in Applied Sciences shall select atleast 30 credits at the 400 level from the Applied Sciences subject area. The 30 credits shall include a four month 8 credit industrial training course in industry.

During the third and fourth years of the special degree programme, the students shall select course units from the subject of specialisation at 300 and 400 levels, so that their credits will add up to at least 12 per semester. The relevant department may specify the remaining course units that should be offered. Further, the special degree students will do a research project, in addition to following course units, which will carry a maximum of 6 credits.

Students following the Statistics and Operations Research or the Computation and Management degree programmes shall select course units specified for these programmes.

Following subject combinations will be offered under Physical and Biological Science streams (There should be a minimum number of 10 student enrollments to offer a combination).

Completion of Degree

Students should complete all three year degree programmes within five academic years from the date of admission to the Faculty. In the case of students offering a four year degree, this period will be six academic years.

Entries in the Transcript

Course units with the corresponding grades and grade points obtained will appear in the transcript. F grades which have been upgraded will not appear but the credit earned of the repeated course unit will appear under the particular semester when the unit was completed with a label (R) to indicate that the course was repeated. F grades which have not been upgraded will appear in the transcript. The final Grade Point Average (GPA) and the Class (if any) will also appear in the transcript. The transcript will be issued upon application and the payment of a prescribed fee.


Note: Changes to these rules and regulations may be made by the Faculty Board with the approval of the Senate of the University of Peradeniya
