If you’re working full time, you might not want to go out every weekend for classes, and that’s where online programmes can change the way you give your skills an upgrade. Oxford Home Study College, Udemy, Skillshare and Coursera are some of the popular websites that offer a wide variety of courses {that are free, for the most part} on topics like artificial intelligence, applied data science with Python, postwar abstract painting, courses on Google AdWords and more.
They’re all legit websites that also provide you with completion certificates, so don’t worry, there’s just everything to gain.
