What are the job opportunities available in computerscience field?

A degree in computer science focuses in the thinking and talents that are required to work in high tech jobs, such as programmer, software engineer, QA etc. Just remember that the degree is very tough in comparison to other academic degrees and you need to maintain a high average if you want to be considered when applying for a job. Just how high that average must be, I can't tell and it will depend on the market (supply-demand) in your country.

Good luck.
