What's the ideal time to spend on sololearn a day for you to be advanced?
A couple of hours a day or more, if done consistently, if you are a beginner would be good.
First of all, 6 hours is a lot, and only using sololearn may not help to get advanced, because it is just to help you get started; second of all, you can use the description to add a description, instead of answering your own question
I would say 6hours is enough for you to advance at a fast rate
True using only sololearn won't make u advance
