The best back end course

Answer 1

But I think the best way is trying maximum, it means both SoloLearn and FreeCodeCamp and maybe Programming Hub or w3schools certification (W3 is the biggest programming company — HTML, XHTML, SVG...)

Answer 2

If you think SoloLearn isn’t good try FreeCodeCamp (works only on PC; https://freecodecamp.org)

Answer 3

Or if you can pay, try Programming Hub (on Play Store and App Store)
