Are you on sololearn to teach yourself, or are you in college and use it to get the basics or to compare? Can you advise a plus?
Sololearn is definitely one of the best,if not the best,apps out there. But,we can only get this much. SL does a good job for a free and easy to use app, to provide with the basics and sum up the content of some languages.Now they doing even better by adding contents and, for a self teaching like me, curiosity is what guides me. That's why I want to know how the most experienced users do,what they can advise when you have limited resources (using Mobile), what book, how to interact with the community etc
