If you’re like most people, when you think of computer science, you may immediately think of a dark room with a bunch of people huddled around computers furiously typing away at their keyboards, or you may even think of complicated maths and number based computer related programs. However, there a number of things you may not know about this profession.

For example, computer scientists will more often than not, focus on the theoretical aspects of computers, which then serves as a big umbrella with a broad range of subjects and career opportunities underneath it. This field focuses on the study of computers and computing, including the theoretical and algorithmic foundations, hardware and software, and their uses for processing information.

Computer science has become a booming market across industries, as the world becomes more and more dependent on computers and technology. According to the Bureau of Labor Statistics, the computer science field is growing faster than usual with a 16% growth rate per year!

Pursuing a career in computer sciences means that there are many industries and career paths that will need your highly valuable skills at one stage or another.

There are plenty of opportunities to gain the knowledge and skills to become a successful computer science genius. One of the most popular choices is online learning. We have searched the internet to find some of the top-rated computer science courses available at the moment. So be sure to check out the links below to kick-start your computer science career.

What the reviews are saying:


I’m the type of student who doesn’t like courses that are too slow or too hard. I’ve taken countless online courses and over 10 udemy courses. There is not one course that has kept me wanting to move forward the way this course does. I usually wait until I’m around 11% through the course and if I still feel stuck then I drop it. This guy is not an Instructor, he’s a straight up mentor. Whenever I need help he’s there to help on challenges that’s in this course and/or my personal challenges (ProjectEuler, which is an online programming site for challenges). I use to be scared of programming challenges and now I’m feeling more and more comfortable. And yeah, he does facebook chat too if you really need serious help. Whoever gives this guy a rating of less than Excellent is a fool and they never gave him a chance to show how amazing of a teacher he really is. I’m now at 57% percent and still going. CAN’T WAIT FOR PART TWO!!!!!” – Ralph Guichette
