Is the APUSH Crash Course Series enough to study for the AP Test?

If I watched and studied all the APUSH Crash Course videos, would it be enough to score a 4 or 5? Or would I also need a supplement like AMSCO?

Also, by “watched and studied” I am referring to both the Crash Course videos and the Crash Course book. I have AMSCO readily available as well, but am not sure which one is more helpful.

I used the Crash Course book too but since it only has a few practice questions I’m also using Princeton for practice tests/essays
