KD bro, transcripts are a consolidated marksheet, stamped by the Controller of Exams/ Registrar of the Uni.
they are needed by 'evaluation authorities' like WES etc,
to check where our degree/course stands in comparison to Canadian degree/course.
suppose we hv to do MBA, or any masters course, we wud need to clear their UG course,
if we get a positive evaluation report for our UG, we can get directly into the PG course.
hence it saves a lot of things.
as u r focussing on CGA like me
u got to have it, made and sealed in uni. envelope.
it takes 2-3 weeks by indian unis, so apply asap.
also, get at least 5-7 sets.
WES, needs transcripts along with the syllabus, and the system of clearing the exams (obtaining passing marks)
dhakke kha kha ker Delhi uni key, sub arrange kia, and today got it all sealed in DU envelopes.
but yes, they were supportive and systematic.
rest, amit has described aptly.
