Which link should I paste in project link section while answering the certification test?
I have submitted the project in projectsubmission.boltiot.com.
@akshayphadke002 you have to give the Preview Link of your project which must be pending in the Project Submission site. The Bolt team will review it and give the marks after you submit your final test.
Do close the query, if you find it useful, by clicking on the Solution button 
But when I open that preview link in the browser, it shows Page not found.
@akshayphadke002 it’s just normal. You can only see the draft but if you will try to see the project via the preview link you won’t be able see the project.
You have to submit that project link in the Certification test and the team will review your project internally. Don’t worry
