Complete the university program. Before starting a Master’s or PhD program, you need a Bachelor’s/Engineer’s degree. Ideally, your undergraduate degree will specialize in a field related to computer science, math, or any other closely related discipline.

However, with a high enough GPA and standardized test scores, it is possible that you will be accepted into a graduate program without a bachelor’s degree in computer science, especially if you can demonstrate interest. long-term and gifted in the field of technology.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/71/Study-Computer-Science-Step-12.jpg/v4-728px-Study-Computer-Science-Step-12. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/71/Study-Computer-Science-Step-12.jpg/v4-728px-Study-Computer-Science-Step- 12.jpg”,”smallWidth”:460,”smallHeight”:337,”bigWidth”:728,”bigHeight”:534,”licensing”:”<div class=”mw-parser-output”></div> “}

Take the appropriate standardized tests. With most graduate schools in the US, you will have to take the GRE (Graduate Record Examination) – a test that tests analytical, quantitative writing, and reading/language skills. ^{[12] X Research Source}

With an advanced degree in computer science, you need to be highly skilled with numbers. Therefore, quantification should almost certainly score excellent. High scores in other areas are also important for acceptance by competitive training programs. However, they often rank slightly behind the quantifiers.
In the University of Chicago’s Master of Computer Science program, for example, successful applicants typically score in the upper tier: at least 50 percent in the language section and 20 percent in the quantitative section.
If you are applying to a school in the US, you may also need to take the TOEFL (Test of English as a Foreign Language). ^{[13] X Trusted Source Educational Testing Service Go to source} Check the program you want to study for requirements to be met.
