The course is considered as a foundation course for
students who want make their career in the field of Science. It is
offered in a variety of Science subjects at a majority of universities
in India. Some of the popular B.Sc courses that students usually choose
to pursue after Class 12th are B.Sc Physics, B.Sc Computer Science, B.Sc
Chemistry, B.Sc Biology, B.Sc Mathematics, and so on.
A B.Sc course can be pursued as both a full-time or part-time course.
Students can choose to pursue plain B.Sc or B.Sc (Honours). The course
is most apt for students who have a strong interest and background in
Science and Mathematics. The course is also beneficial for students who
wish to pursue multi and inter-disciplinary science careers in future.
What is B.Sc Eligibility?
In order to study B.Sc, the students should meet the below-mentioned eligibility criteria:
- The basic eligibility is to have 50-70% in Class XII from any recognized board.
- The students must have core subjects like Maths, Physics, Chemistry and Biology in their Higher Secondary level.
- The age limit to take admission in B.Sc courses is minimum or above 18 years.
B.Sc eligibility criteria may vary depending on the college chosen and the candidate must meet all the criteria to get admission in top colleges offering B.Sc
Why pursue B.Sc?
There are many advantages of this course, some of them are mentioned below:-
- B.Sc courses provide deeper subject knowledge and practical knowledge in a chosen branch of science. It is mostly pursued by students who want to contribute in research and development.
- Skills developed after a B.Sc degree are Research skills, Observational skills, Problem-solving skills, Logical skills and Experimental skills.
- Students who wish to pursue multi interdisciplinary careers in the future can also go for this course.
- This course imparts knowledge regarding certain areas in four main science subjects, physics, chemistry, maths and biology.
- After successfully getting a B.Sc degree, one becomes eligible to earn INR 2-5 per year
- Various industries like Laboratories, Pharmaceutical Companies, Educational Institutes, Cosmetics Industry, Health Care Industry, etc are open to hire these graduates.
- Future benefits of this course include increased theoretical and practical knowledge and developing research and experimental skills required in any research-based organization or institute that will prepare students for many diverse and exciting careers.
