Hello Alpha ;) 

Great job of you working on the Rapid Developer course and great question post! 

From my perspective it shouldn't be necessary to continue doing only courses. What I advise you to do is get practical and try to find a real world project from the company you're working at or get a friend with higher experience find development tasks for you. 

This is the best way of learning. That being said, that doesn't mean you shouldn't continue at all doing courses / learning paths. What I would advise you again is to have a goal in mind when doing anything, In this case your goal should be the intermediate certification. These are the necessary learning paths for the intermediate exam:

• Unlocking True Collaboration
• Constrain Your Data Using Xpath
• Create an App with Advanced Page Building
• Building an Event App using Microflows
• Expand Your Domain Modeling Skills

Thanks Marcian!
