Hello najim!

Please tell the exact name of exam so that I can check accurately that whether any kind of registration fees is required to appear for the exam or not. Without the specific details i won't be able to check.

You can visit the official website of the agency conducting exam then apply for it if it requires a fee for registration then yes you will have pay to certain amount for appearing in the exam.

Please reach out in case of any other query regarding the same!
