B.Sc. Degree programme is designed to contribute towards raising the general educational standards of the public by providing an opportunity for higher education in Science. This programme facilitates those already employed in the field, and late developers to acquire a B.Sc. degree in their own time at an affordable cost. It specifically aims to:

(a) provide an opportunity for persons to obtain a Science Degree and thereby improve their promotional/career prospects

(b) enable, particularly those already employed in the field, late developers, and those who could not avail themselves of higher education at the end of their secondary school career to obtain a degree

(c) enable any person to pursue a degree course in Science in their own time at an affordable cost

(d) combine courses within and outside the Faculty to suit a student’s interest or job requirements.

The B.Sc. programme offers courses at Levels 3, 4 and 5/6, equivalent to the 1st, 2nd, and 3rd years of the B.Sc. Degree programme of a conventional university. Depending on the qualifications, a student can choose three disciplines from Botany, Chemistry, Pure Maths, Applied Maths, Computer Science, Physics or Zoology for the B.Sc. Degree.

Enrolling to the BS Degree programme in the Faculty of Natural Sciences enables you to make a choice at the end of level 4 (second year) to continue in the OUSL or join up with the BSc Degree in the University of Essex, UK through progression link. At the completion of level 5 (third year) if you are eligible to register for a Special (Hons.) Degree in the OUSL, you will be able to gain direct entry to the MSc programmes in University of Essex, UK.
