Rawdah,
It seems that you are almost touching 35
, just kidding.
Well, I was observing that almost everyone is asked to fill in from the age of 18 but most of the MR guys, they weren't asked. That is why I wanted to dig out if Maria & Farhan have filled in from the age of 18 or recent 10 years.
I think, If applicant(s) is 30 to 32 he/she might not be asked to update Schedule A by filling in from the age of 18 but all 32+ will have to update it, unless they have already submitted Schedule A from the age of 18.
By the way, you must disclosed your age as you are not asked to submit by filling in from the age of 18 so that your case may become a basline for everyone.
