Oh, God! This is actually sending me chills. Actually, the Master diploma are the words mentioned in the certificate and I studied it from an institution named CADD Centre. It neither a college nor falls under a university or something. I doubt if the certificate has somekind of value outside India. They dont even conduct any exams to provide marks or something. At the end of each subject, we ll provide a project which leads to a certificate as Master diploma in product design. They dont have a grading system and also IRCC requires those marksheet, grades or percentage. So there ll be nothing to show other than a certificate. And that is why I chose not to show this on my profile.First of all it is a serious offence to hide any information in your profile(In this case you not mentioning about your masters since it is your last qualification). If they find out they can consider it as misrepresentation and can issue a ban for five years. Looking at the profile your course seems to be the biggest cause out of all. Going for a certificate course after having work experience is not in favor these days in the eyes of VOs. I am seeing a lot of rejections in certificate courses after pandemic began.
Going for another masters or phd is your best option. Give strong reasons on how a relevant course in Canada will help you back in home country. Also make sure to explain each and every concern of VO once you receive your GCMS notes.
Back again to the masters you already have. imho you should not hide it. Even if you get away this time they can still find it out in the future and you might face huge repercussions. Wait for others take on this matter and do accordingly. It is not worth the five year ban over a rejection.
I highly doubt that any university would accept 67% and a second class degree. So that doors are closed. Certificate will be the only way to go I guess. Any suggestions on this?
