Hi
Advance diplomas are generally done after 12th and are of 3 years. if you are talking about pg diplomas, it is also known as a graduate diploma and offers people with a relevant undergraduate degree a chance to improve their employability skills. The postgraduate diploma is usually offered as a12-month course and requires students to complete a specific number of learning credits for the institution to grant the diploma to the student. Additionally, a number of postgraduate diplomas offered by leading Canadian institutions include a short work component, which allows students to hone their skills in a real industry environment.
Master's on other hand is a degree of 2 years again and gives you specialization.

Dear Vansh,
About 3 years back a student of mine had got admitted to the UK after having done his BCom from Karnataka open university, however, the UK University had written and asked the KOU to send their attested copies of his transcripts directly to them and the student had to go to the KOU and pay them the required fee to get it done. I am not sure with Canada and Australian institutions about this, suggest you check directly with the Universities you intend to apply to, send a mail to the International Admissions office id can be got from the Universities website. The other solution is to get your qualifications evaluated by WES which will cost you about Rs.12,000/- but payable in dollars by credit card.
