FSW application, just starting!

Hello
Im new to this forum & am starting the paperwork to go to Canada.

My hubby is the main applicant, but the forms ask for my education... I cannot find any paperwork so have been phoning around....

I did a sponsored course through one employer (20+ yrs ago) & that company no longer exists!
I cannot track down any 'trace' of my qualification...the body that governs it dont have a record of me...as i do not intend to work in that trade (optics)... do i declare it as part of my education (but cannot back it up, do i risk mis-representation?)...or leave it at only the GCSEs etc that i can get evidence of?

Ive tried to contact the High Commission (cant get past the auto-phone system to speak to the right human!) spoken to the education authority from my area who couldnt help...

PLEASE HELP! panic at the first stage...any advice is welcome...
