Frequently asked questions

How are PDE exam questions divided by domain?
The Google Professional Data Engineer exam covers 9 domains. Each domain carries a specific percentage weight in the exam blueprint. Practicing by domain lets you allocate study time according to each domain's weight.
How many questions should I practice per domain?
Start with a 10-question session to identify your baseline. Once you can consistently score above 80%, move to a 20–30 question session to test depth. Revisit weaker domains before your exam date.
Can I practice all domains for free?
