Hello,

Since you have not appeared for CS exams after 2016, your registration may have expired. Here’s how you can proceed:

1. Check your registration status with ICSI by contacting your regional office or emailing them.

2. If your registration has expired , you will need to apply for de novo registration . After renewal, you can continue from the same stage without losing previous exemptions.

3. If your registration is still valid , you can reappear for the remaining two papers (Insurance and Taxation) in the next exam session.

4. Check the latest syllabus , as the papers may have updates. Prepare using the updated study material.

In short: check your registration, renew if expired after that, prepare as per current syllabus and appear for remaining papers.

Hope it helps !
