Hey Sonam,
the advanced exam requires experience over theoretical knowledge. Just following the advanced learning paths isn't sufficient.
You should have a good grip on how Mendix works and how the implementations take effect.
You should carefully follow all of the learning paths and get a good understanding of them as well.
All the best with the exam.
:)
