GCP PCA exam in 2 weeks

Hi guys, I’m gonna sit for PCA exam in 2 weeks. I just passed my cloud engineer associate few months ago. Is the course gap huge between these two?

Would really appreciate if you guys can share some good resources to prepare from and practice tests as well. Im gonna go for tutorial dojo or sayyam, which practice tests should I choose between these two or if there are other solid ones besides these two?

For theory, im studying from ragna’s PCA course
