I completely tanked my first attempt at CCD-102 because I was just reading through Salesforce B2C Commerce and SFRA official documentation without actually coding or testing anything. Thought understanding the framework theory would be enough, but the exam tested practical application in ways I wasn't ready for.

Got frustrated and switched to itexamstopics.com web version instead. Their practice tests actually simulated real exam scenarios with SFRA development concepts. The demo questions upfront showed me the specific areas the exam focused on. Instead of passively reading docs, I was solving actual questions about commerce development and learning from every wrong answer. Two weeks of grinding through their practice tests and I passed on the retry. If you're prepping for CCD-102, ditch the documentation approach and jump into their practice questions immediately. Their questions cover the real exam format and you'll understand what's actually being tested.
