Hello Ramesh
In most cases you would require an IELTS score to study in Germany. However, you do not need an IELTS if you hold a bachelor's degree which was taught in English or if your mother tongue is English or if you stayed or worked in a country where English is the official language, and this will depend entirely on the university's admission rules.
German universities offer the programs in a very reasonable budget for international students. German national universities are free of cost and are extremely competitive to get into. They may charge a small amount of semester fee from international students. Even private and other public universities are quite cheap. This is why they are selective and admits only the selected outstanding students. You need to check university websites for more details.
Hope this helps. Good luck with your future.
All the best!

Hi Aman,
Computer Science is the study of computers and computational systems. 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 theories of computing. Computer scientists design and analyze algorithms to solve programs and study the performance of computer hardware and software.
Many people incorrectly believe that a computer science career is all about programming. While it is true that most entry-level jobs after a Bachelor's degree involve programming, most practitioners eventually graduate to other responsibilities such as design, coordination, testing, planning and management. With advanced coursework and a Master's degree, you can work in an area of specialization that uses your advanced coursework.
Also education in Germany is government funded, there is a possibility that you might have to pay a minimal fee ranging from euro 140-500.
For more information on German Universities, I would request you to visit the nearest DAAD office. DAAD is officially authorized to provide information about education in Germany. They have offices in major cities in India.
If possible go for a German language course as it will help you find a part time job. A student in Germany can work 90 full days or 180 half days.
Hope this information helps. Please feel free to revert.
Wish You Luck!
