Hello.

I don't understand what you mean by top 4 subjects or courses ? That's okay however iam going to give you some clarity about that.

Computer Science is the study of computers and computational systems. Unlike electrical and computer engineers, computer scientists deal mostly with software and software systems; this includes their theory, design, development, and application.

Principal areas of study within Computer Science include artificial intelligence, computer systems and networks, security, database systems, human-computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, bioinformatics and theory of computing.

Although knowing how to program is essential to the study of computer science, it is only one element of the field. Computer scientists design and analyze algorithms to solve programs and study the performance of computer hardware and software. The problems that computer scientists encounter range from the abstract-- determining what problems can be solved with computers and the complexity of the algorithms that solve them – to the tangible – designing applications that perform well on handheld devices, that are easy to use, and that uphold security measures.

Here are the top 6 jobs you could get with a computer science degree:

• Full Stack Web Developer. A full stack web developer is well-versed in both front- and back-end web development.
• Mobile Application Developer.
• Software Engineer.
• Systems Architect.
• Machine Learning Engineer.
• Data Engineer.

Basic eligibility for Bsc

Eligibility for Bachelor of Science [BSc] The minimum eligibility criteria for this course is as follows: Candidates must obtain 50%-60% aggregate marks in 10+2 examination with Mathematics as one of the subjects.

Hope this is helpful.

Good luck.
