Nothing is ‘established’ - the transcript supposedly from the U of WA has no provenance, it was sent to the recipient as a scan BY E-MAIL.
It’s as ‘genuine’ as the Hawaii Certification of Live Birth.
The ‘transcript’ shows commencement as August 19. The semester didn’t start until September 25.
Now let's to this the long way...ONE YEAR PLUS 1959 = JULY 1960.
add another SIX MONTHS = JANUARY 1961.
