Congrats on completing the full pathway, that is a solid milestone.
One thing that made a big difference for me was trying to translate the learning into a real end to end use case, especially building a simple pipeline using the medallion architecture (bronze, silver, gold) instead of keeping things only at the module level.
It really helps to understand how ingestion, transformation, and serving layers connect in practice, not just individually.
Good luck with the certification as well.
