While the exam is updated with every release, these changes are minimal. Your certification exam will cover the same basics either way.
So, just go and get it. 🙂
How did I get it, with minimal Salesforce experience?
- I invested in a two-day training.
- I studied the platform for two weeks.
- I got to Mountaineer status on Trailhead.
That being said, I absolutely recommend you get actual Salesforce experience, before taking the exam. It’ll be lot easier and require less studying.
