B.Sc Computer Science Course Details

A typical department gives two thirds of the contact hours to teaching and one third to the laboratory, and the laboratory is where the subject becomes real. The first year builds the programming habit, the second year deals with data and machines, and the third year turns to systems, networks and the project.

How the semesters usually run

Semester	Focus
Semester 1	Programming fundamentals, computer system architecture, mathematics for computing, digital electronics and a language paper, with the first software laboratory
Semester 2	Data structures, object oriented programming, calculus, probability, and the software and digital electronics laboratories
Semester 3	Design and analysis of algorithms, operating systems, computer networks, algebra, statistics and the software laboratory
Semester 4	Database management systems, software engineering, programming paradigms, differential equations and the software laboratory
Semester 5	Artificial intelligence, computer graphics, theory of computation, internet technologies and the elective papers, with the project work starting
Semester 6	The elective papers and the project or dissertation, with a viva and, in some universities, an industry or academic internship

B.Sc Computer Science Eligibility Criteria

B.Sc Computer Science eligibility particulars	Requirements
Qualifying examination	Class 12 from a recognised board, with mathematics as a compulsory subject, and often computer science or computer science with informatics practices
Minimum marks	At least 50 percent in the aggregate, with a relaxation of 5 to 10 percent for reserved category candidates at several universities
Subject combination	Central universities set a combination rule, and the University of Delhi asks for mathematics with two other subjects from the science list, or with a language
Entrance examination	CUET UG with the computer science domain paper for the central and participating universities, or a state or university entrance test
Age limit	Some central universities apply an upper age limit for the undergraduate programme, and the limit of the admitting university applies
Lateral entry	Several universities admit diploma holders directly to the second year through a lateral entry scheme, with a separate entrance test and a fee
Medical fitness	A medical fitness certificate is usually required at the time of joining

Mathematics is the subject that decides the application. A Class 12 without mathematics does not meet the requirement for the degree at the universities that set this rule, whatever the rest of the marksheet says.

Keep your Class 12 marksheet, the category certificate and the migration certificate ready
Check the subject combination and the minimum marks of the university you are targeting
Check whether the university applies an age limit and whether a lateral entry scheme is running
Take the entrance test that the university actually accepts for the programme

B.Sc Computer Science Admission Procedure

Most universities publish one notice a year that covers the entrance, the counselling and the document check. The steps below describe that common flow, and the dates and the documents are the ones printed in the notice of the university.

Step	What students should do
1. Register for the entrance	Apply for CUET UG, the state entrance test or the university entrance test, and pay the application fee in time.
2. Appear for the examination	Sit the test, choosing the computer science domain paper where the test has one.
3. Take part in counselling	Join the counselling of the university, which for the central universities runs through the common allotment process.
4. Submit the documents	Upload the Class 12 marksheet, the category or disability papers and the other records listed in the notice.
5. Accept the allotment	Accept the seat, pay the university fee and confirm the date of joining.
6. Report to the college	Join the college, complete the orientation and the bridge course if one is offered, and start the first laboratory.

Documents required

Class 12 marksheet and certificate
Entrance score card and the counselling allotment letter
Category, disability or economic weaker section certificate where applicable
Transfer certificate and migration certificate from the previous school
Government photo identity document, recent photographs and a medical fitness certificate

B.Sc Computer Science Entrance Exams

The entrance for this degree has moved towards a single national test, with the state tests still running alongside it.

Exam or route	Conducting body	Where it applies
CUET UG	National Testing Agency	The national entrance used by the central and participating universities, with a computer science domain paper and a general aptitude paper
State entrance tests	State examination authorities	The engineering and science entrances of the states, used by the state universities and their affiliated colleges
University entrance tests	The admitting university	Entrances run by a university for its own seats and for the colleges affiliated to it
Lateral entry test	The admitting university	For diploma holders seeking direct entry to the second year of the degree

Note the change at central universities. Banaras Hindu University now admits through CUET UG only, and its separate entrance test no longer runs, so a candidate who plans a central university has to plan the CUET date first.

The score used for admission is often a combined one. Some universities build the merit list from the entrance score and the Class 12 marks together, while others use the entrance score alone, and the weight given to each is printed in the information bulletin of the university.
