When you have completed all courses available which I have have seen some people do. How do you continue to sharpen your skills?
Yes, you can practice to write code from Code Playground.
Completed the courses in SoloLearn is just a starting point in learning coding. You should start to use what you have learnt and apply to code writing and testing. Learn by building simple test applications. When you are ready and have acquired enough coding experience and skills, you would start to build real applications.
Thanks, this can be done from with in this app?
Practice. Just practice and apply what you learned.
Devon Charles, you can build some stuff for practice in the code playground but it is basic programs.
