While we'd love to add every feature possible to Teachery, quizzes, questionnaires/surveys, forms, and completion certificates are not on our development roadmap at this time.
However, we have some recommendations for you that use our powerful "Add Content Block" feature within your course lessons:
Google Forms is a great, simple free option for creating embedded quizzes.
Tally's Free Quiz Maker (recommended tool) is gaining popularity and if you're familiar with Notion, you'll really enjoy using their interface (free plan available too!)
Typeform's Quizzes are a solid option with a lot more functionality and brand-ability. They have a free pricing plan to start, but it is limited.
There are many other quiz/assessment tools available and if a tool you find offers embed code (script or iframe), that can be added to any lesson within Teachery 
.
You can easily create your own course certificates using Google Slides, Powerpoint, Keynote, Canva, or other certificate-creation programs.
In Teachery, you can include these certificates as a link in your Course Completed email (an email Teachery sends to your students once they complete a course).
