Is it good to just focus on one course or learn a few at a time? (C++, C#, etc.)

Question

I was just curious because I love learning this and wanted to know if learning one at a time was the most effective or learning some courses at the same time was a good idea.

Answer 1

learn one course at a time . leaning many courses will mess up everything in your mind.
Also don't completely rely on sololearn for learning.
sololearn just gives basic idea of couse but it's excellent for practice and supportive community
