SAT / ACT Prep Online Guides and Tips

Thinking about getting a computer science degree? You've probably heard that there's huge demand for computer science graduates, and students who major in computer science can expect high-paying jobs right out of college. But computer science programs have very high dropout rates, often because students choose this major without really understanding what it'll be like.

The best way to avoid this is to know what to expect going into a computer science program, and we're here to help! By reading this guide you'll learn:

• What is a computer science degree?
• What do computer science majors learn?
• Is computer science the right major for you?
• What are the best schools for computer science?
• What can you do with a computer science degree?

What Is Computer Science, and What Is a Computer Science Degree?

Computer science majors study computers and different programming languages to learn how to design, develop, and test software programs and applications. Students in this major take classes in calculus, electronics, computer systems, probability, programming, and algorithms.

Computer science focuses primarily on software, and computer science coursework might focus on analyzing large datasets, understanding different programming languages, cybersecurity, and coding. If you get a computer science degree, you are expected to be well-versed in each of these areas.

Computer engineering is similar but includes more coursework in electrical engineering as students are learning more about the computer hardware compared to computer software.

Majoring in Computer Science

As with other bachelor's degrees, it generally takes four years of full-time study to earn a bachelor's degree in computer science (sometimes called a "CS degree"). Some people can complete it in 3 or 3.5 years, especially if they have credits already earned from AP or IB scores, and some people take closer to 5 years, especially if they get a double major or take more classes beyond their computer science requirements. It's also possible to get an online computer science degree from many schools as online college classes become more popular.

As a computer science major, you'll have to complete university graduation requirements like all other students. These often include one or two writing classes, a math component, a humanities requirement, and a social science requirement. Additionally, you'll also often have to take a few science-related classes in biology, chemistry, and/or physics. This is because most computer science majors earn Bachelor of Science degrees, and those often have both math and science requirements students must meet. The math requirements can be extensive, with required classes in calculus, statistics, and linear algebra, among other subjects. Most of your classes, however, will be directly related to computer science. 

Common classes computer science majors take include:

• Introduction to Programming
• Computer Systems
• Software Design
• Software Engineering
• Computer Organization 
• Algorithms and Data Structures
• Ethics in Computer Science
• Algebra
• Statistics
• Operating Systems
• Computer Graphics
• Artificial Intelligence
• Computer Security
• Programming Languages
• Data Analysis
• Mobile Application Development

Of course the exact classes you take will vary based on the school you attend and your own interests, but expect to have a solid grounding in math and science as well as in-depth knowledge of computer programming, software design, website creation, and more.

Is Computer Science a Good Major for You?

A computer science degree can lead to many high-paying job opportunities, so it's a popular major for college students to consider. Computer science is often ranked one of the best majors for college students because demand is steadily growing for their skills, and they can often land high-paying jobs right out of college. According to the US Bureau of Labor Statistics, software developers (one of the most popular careers for computer science majors) have a median salary of $107,510 a year, and demand for the career is expected to increase 22% over the next decade, which is much faster than the average job growth of 4%.

So a computer science degree could be the path to wealth and a stable career, but does that mean it's what you should major in? There are important considerations to take into account. Many students, lured by the benefits of a computer science degree, choose it as their major only to later switch to a different program. In fact, a UK study found that computer science majors are more likely than any other major to drop out of their program.

Why is this? There appear to be two main reasons. First, to be blunt, computer science is a tough major. You need strong skills in tough subjects and a lot of technical know-how. Early classes are often designed to be "weeder" classes that are deliberately tough to get students who aren't ready for the rigor of the major to drop out early. Computer science classes also build on each other, so if you scrape by in a beginner class, your lack of knowledge will come back to haunt you again and again in future classes. It's not a major where you can cram at the last minute, forget what you studied hours after the exam, and come out OK. Final exams can often be 50% or more of your grade in a class, meaning you can't mess them up and still get a good grade. All of this combines to create a major that requires consistent hard work to do well in.

The second reason computer science is commonly dropped is that many people find that the classes you take and the skills you learn for a computer science degree simply aren't interesting to them. It's common for students who enjoy video games, phone apps, etc. to think that they'll enjoy learning the process behind creating one of their favorite hobbies. However, learning how to code, studying statistics, deciphering algorithms, etc. is very different than actually enjoying the finished product of many of these skills. This lack of interest, combined with the challenging workload of the computer science major, causes many students to leave the program.

Many students change their major in college, and sometimes it's unavoidable because the best way to learn whether you like a subject or not is to actually take classes in it. It's often quite easy to change your major, and it may not even delay your graduation, but having at least some idea of what to expect from majoring in computer science can make it more likely that you choose the best major for you from the start.

There are many ways to get a taste of what computer science classes will be like before enrolling in college courses. Codeacademy offers free coding classes, and Harvard's online learning site, Coursera, and edX all offer computer science classes, many of them free. Give a few of them to try, and see if the information you're learning is something you think you'd like to continue studying throughout college as well as throughout your career.

The 8 Top Computer Science Programs in the US

If you decide you want to get a computer science degree, you'll want to make sure you're going to one of the top schools for it. Below are eight of the best undergraduate computer science programs in the country.
