The challenges have no effect in being able to claim a certificate or not
But you should know that new certificates have come out that requires different projects
you can still claim the old certificates from the settings if you complete the projects you have not done yet, you will find them in the Interview Prep section, under “Take Home Projects”
What determines whether you can claim a certificate or not?
Once you have done all the projects for that certificate you can claim it
In the past I did a Twitch and Wikipedia API project. I can’t find them in the curriculum, are those 2 project swapped out for different projects?
You can still complete the legacy certificates from the settings, you can find the projects needed (that are no more used in the certificates) in the Interview Cide Prep section under Take Home Projects
If you finish all the required projects for that you can claim them, for the new certificates you need different projects
