Hi @Nihad Arif 

From August 2022 to now, September 2025, there has been a 3-year gap during which ServiceNow released 6 major updates. Now, you need to start from scratch, which means completing the CSA training again and appearing for the exam.

The current version of the exam is Yokohama, and once you complete it, updates will come later. The major change now is that the delta exam needs to be taken only once a year.

The good news is that Now Learning courses are free, and you only need to pay for the exam. Also, if you are a resident of India, you can use the NASSCOM coupon code to get a 50% discount.
