Ok there are two options going forward
1. If you have 30 hours of flying experience within the last 3 years ( this time period can be argued) then you can renew for lifetime without giving any exams
Pay with dd of 10,000 rupees and renew for lifetime
2. If you dont have 30 hours within the last 3 years you need to give the Part 1 exam at the upcoming Mumbai attempt in Feb
Once you pass then pay a DD of 10,000 rupees and renew for lifetime
