Hi @Naresh_5120,

The fee is 300 USD + sales tax depending on your county of residence. 

With the migration to Pearson you can retake mainline exams as many times as needed. A retake fee is required for each attempt and a waiting period between the re-takes will be enforced by the system.

All questions regarding exams with Person and retakes are summarized in the following KBA: https://learning.servicenow.com/lxp/en/credentials/transitioning-from-webassessor-to-pearson-vue-faq...

Hope this helps!
