After doing B.Sc. in computer science, there are many options for enhancing ones knowledge and skill and primarily it depends on the interest and liking of an individual. You have to do some introspection in this regard as what is your aptitude towards career. Is it programming or data management or hardware installation and maintenance or web hosting or digital marketing
or data science or animation or software development and analysis or software testing? If you can identify your area of interest, working in which fascinates you, then it will be easier for you to pursue it because a person generally works with full vigour in his area of interest.
