To take a free online course, the first step is to decide what you want to learn.
And there's more: if you can't decide between one topic or another, you can also start with a knowledge trail. Trails are currently available with diverse content for those who: want to make an extra income or start a new venture in the comfort of their own home, work as an operator or inspector in supermarkets, become a Front End or software developer or want to start a business, but don't even know where to start.
At Cursa you will find courses to increase your professional qualification even if you are unemployed, since the courses are free and even certified. In this way, you can take advantage of your free time to study and can also include them in your resume, increasing your chances of getting a good job in the job market.
