Welcome to the community @yugchoubey, I’m happy to share a few tips @PamCotton 
Since you’re already working on the digital marketing path, I would suggest leveraging your HubSpot account to test out some of the ideas shared in the courses.
If you can’t expirement in your main/company account, you can either create a free account for yourself or create a developer test account to access the tools and create tests to get a deeper understanding of the features available.
Depending on how you plan to use digital marketing and what you’re career goal is, it could be helpful to create a free account and use yourself as the brand - post to social, create landing pages, build a free website, etc. to showcase your new skills!
