Can I take free data structures and algorithms courses on Coursera?

Yes. You can start learning data structures and algorithms on Coursera for free in two ways: Preview the first module of many data structures and algorithms courses at no cost. This includes video lessons, readings, graded assignments, and Coursera Coach (where available). Start a 7-day free trial for Specializations or Coursera Plus. This gives you full access to all course content across eligible programs within the timeframe of your trial. If you want to keep learning, earn a certificate in data structures and algorithms, or unlock full course access after the preview or trial, you can upgrade or apply for financial aid.

What will I learn in a data structures and algorithms course?

You’ll learn how to store and organize data efficiently using data structures like arrays, stacks, queues, and graphs, and how to solve problems using algorithms for searching, sorting, and graph traversal. Many courses also include practice coding exercises and real-world applications.

Do I need coding experience to start learning data structures and algorithms?

Some experience with programming is helpful, as these courses typically include coding exercises in languages like Python , Java , or C++ . Beginner-level courses often review coding basics before diving into more complex structures and techniques.

Can Coursera’s data structures and algorithms courses help me in my career?

Yes. These concepts are critical for software engineering , web development , data science , and technical interviews. Coursera courses can help you master key techniques, build a portfolio of coding solutions, and earn certificates that demonstrate your technical knowledge to employers.
