On the other hand, if you need a certificate to show off to your potential employer, consider options that might meet your needs.

The Instructor

There is no denying that the instructor has an essential role in a course.

A good course must be led by a professional with many years of experience who can convey his knowledge in an easy-to-understand way. The best way to know the instructor of a course is to read reviews from previous learners.

Hands-on Experience

The best way to understand what you learn after each session is to apply it and real-life examples. So you should consider courses that offer practice exercises or quizzes, such as those offered through Coursera.

Price

You also need to consider the price of the courses when considering them.

The key is to choose something that’s worth your money. Most of the courses on my list are free to try. So you should use that to decide if a course is worth the investment.
