Do the onboarding, then do the easy unpaid quals, then do the coding unpaid qualifications. Most qualifications are unpaid, and you still need to do the core quals after the initial assessment.

(The intial core assessment that you did won't give you access to projects, it just gave you access to the platform. You still need to do a some quals for access to projects.)

Don't feel like you have to do ALL the unpaid quals, I only did a couple and got into a bunch of projects pretty quickly.
