Unitized structure of B Sc Course

B. Sc. course structure of the university periodically undergo revision as per the statutes of the Mumbai University. It is mandatory for the university to revise the subject syllabi every three years so as to keep abreast with modern developments.
Unitized structure was introduced by university since 1977 when 10 + 2 + 3 pattern was adopted by Government of Maharashtra.
Under this scheme B Sc course of University of Mumbai is a three year integrated degree course and is offered in a unitized form.

  • Each unit is of 100 marks.

  • For Science subjects as well as applied component subjects, 100 marks are split into 60 marks equivalent of theory and 40 marks of practical examination; each forming a head of passing.

  • One Unit of Science subject in terms of formal work corresponds to 3 lecture periods and 3 hrs of practical classes at F Y & S Y level.

  • At T Y the time distribution is little different i.e. one unit corresponds to 4 lectures and 3 hrs of practical classes.

Each year science student has to offer total 6 units of science subjects and 1 units of Foundation Course (F Y & S Y) or Applied Component (T Y). Thus every student will give examination of 700 marks in FY and S Y and 800 marks in T Y.
How these units are distributed into various subjects?
Unit system theoretically offers lot of flexibility. For example student can offer at S Y level 3 subjects or 2 subjects thus offering 2 units each of 3 subjects or 3 units each of 2 subjects. However due to practical constraints in every college it boils to down to certain fixed combinations, which is determined by student number (available from year to year), the sanctioned staff strength (as governed by Maharashtra University Act), and infrastructure.



B Sc Course pattern offered by Ruia College:

In Ramnarain Ruia College following is the prevailing pattern (2006 -07)

Year No of Subjects FC / AC Exam Conducted by
F.Y. 3 subjects from available list*
2 Units Each
FC - common to all College on behalf of university
S.Y. 2 from those offered at F Y subjects
3 Units Each
FC- common to all College on behalf of university
T.Y. 1 from those offered at S Y subjects
6 Units
AC - Subject specific University

* Note: Important point to remember is that all possible permutations in this respect are not available. Check with each department / college office / prospectus for available combinations for a given year.


Following is an example describes the work distribution for all three years for one subject: Microbiology It works in a similar fashion for all science subjects

Year Units Theory Papers Lectures Practical No of days of practical*
F.Y. 2 2 6 periods 6 periods 2 (3 periods /day)
S.Y. 3 3 9 periods 9 periods 3 (3 periods /day)
T.Y. 6 6 16 periods 16 periods 4 (4 periods /day)
T.Y. AC 2 4 4 periods 4 periods 1 (4 periods /day)

* Note: The day-wise distribution of practical classes will differ from subject to subject as per the subject requirements, staff and laboratory availability and other time table constraints.


It means that you will have a consolidated total lecture workload / week of:

Year No of Subjects No of Lectures No of Practical Period
F.Y. 3 18 + 2 (FC) = 20 18
S.Y. 2 18 + 2 (FC) = 20 18
T.Y. 1 16 + 4 (AC) = 20 16 + 4 (AC) = 20
