you need to start from your score of the first attempt. focus on the areas where you scored less, try using different materials and of course more practice.
also, I encourage you to review our lessons learned forum , I am sure you will find many similar scenarios that will help you plan better for your next attempt.

Thanks... any tips in analyzing what went wrong and how to improve...

Hello Saurabh,
I encourage you to thoroughly review the PMI PMP Handbook " www.pmi.org/-/media/pmi/documents/public...ssional-handbook.pdf ".

below is an excerpt from the handbook related to your question:

"
Reexamination
You are granted a one-year eligibility period in which to pass the examination. During the eligibility period, you may take the examination up to three times because candidates do not always pass the examination on their first attempt. Gauge your time carefully to leave enough time during the eligibility period to retake the examination, if needed.
Reexamination fees apply to the second and third attempts to pass the examination. Exam Administration Type PMI Member Status US Dollars Euros
Reexamination CBT/PBT
member
$275
€ 230
Reexamination CBT/PBT
nonmember
$375
€ 315
If you fail the examination three times within your one-year eligibility period, you must wait one year from the date of the last examination you took to reapply for the certification. However, after failing a certification examination three times, candidates may opt to apply for any other PMI certification. For example, a candidate who failed the PMP examination three times in his or her one-year eligibility period must wait one year to reapply for the PMP. However, he or she can apply for the CAPM, PMI-SP, PMI-RMP, PMI-ACP or PgMP (and submit associated initial certification fees) at any time.
If your eligibility period expires without you passing the examination, you must reapply for the certification.
