Each learning room has a set of objectives summarized at the top. You can confidently move on through one of the doors after you have completed all of them.
Objectives are always worded in such as way that that is you can answer “yes, I can do this” you pass. This helps with self-assessment, which is itself a skill that takes practice to master. You might consider writing out your responses or speaking them back to yourself at first to get used to it.
If you aren’t confident, perhaps get a friend or mentor to help you make that assessment and improve your confidence. You can look for other people in the same room with you and work out how to escape that room with them. Just remember that ultimately you should be just as skilled as self-assessment as you are any of the skills.
You are not done with the Boost until you feel 100% confident in your ability to set forth a learning plan and self-assess completely independently. Doing this requires the ability to confidently create learning objectives for yourself.
These are critical essential skills of any autodidact.
