Answer 1

Sololearn courses are very easy, they only teach the absolute basics. A certificate is proof of your efforts that you completed the course, but on its own, it will not suddenly make you an expert.

Yes, what Tibor Santa said. You can speedrun through the courses without really learning anything beyond the basics.
