Best Free Online Courses in Computer Science

Best-Free-Online-Courses-in-Computer-Science

Computers form the backbone of our society today. While developed countries are nearing automation in every imaginable sector, developing countries are fast catching up.

The demand for knowledge and practical skills in computer science will only increase with the passage of time. There are also a wide variety of specializations in this field, and thus there is something for everyone. 

Ironically enough, the computer revolution has also changed the way education is provided and received. Today, there are so many new ways of learning which were quite unimaginable even thirty years ago. 

Computers have made it possible to bring close to realization the dream of free education for everyone. Today, it is possible for a student to learn at his own pace and manage his time better.

Earlier, education used to be the privilege of a select few who could dedicate the time and resources consistently.

Now, education can be provided by some of the most prestigious universities in world to students in any corner of the globe.

There are several online learning platforms like Udemy, Coursera, MIT Open Course Ware etc. which fulfill these needs. Keeping this in mind, today we focus on some online computer science courses.

These Best Free Online Courses in Computer Science have been selected keeping the following parameters in mind:

1. Credibility of the teacher/institution

2. Levels – laymen to expert

3. Resources available to the student – study materials, after course updates, interaction with teachers/fellow students.

4. Reviews of previous students

5. Financial aid (whether available)

So let’s get started!

https://medium.freecodecamp.org/450-free-online-programming-computer-science-courses-you-can-start-in-september-59712e77635c

These should be opted for only when the student has an already strong base in the fundamentals of computer science.

Some courses will also require a strong base in programming, physics, advanced mathematics or statistics, coding and even robotics.

Students should satisfy themselves as to the prerequisites before applying for any course. Also, some courses, most notably on Coursera, offer financial aid.

Students should check if they are eligible for such aid and take advantage of the same.

Happy Learning!
