IELTS

Hi Meet, you can get a student visa after getting the admission offer letter from the university. Every university has different admission requirements and with 65%, you won't get too many options in Canada since competition is very high. You can check here:

As far as the best course is concerned, you should know what is best for your future, know what you want and study accordingly. Every student has different aim and interests, you should follow yours. See the above link for suitable programs and decide.

Hi Arash,
Admission will be little competitive since higher grades and better IELTS scores are required. But they have foundation or pathway programs which can be offered to you. It will depend on the university or the college. You can email them, they will guide you accordingly.

Hi Bansal,
These many backlogs won't be accepted so the answer is yes, problems will be there. Even if a college does accept there is a chance of visa rejection. You can try applying but also check universities in other countries which are known to be less competitive than Canada like Poland, Ireland, Sweden, Ukraine, etc.

Hi Nikhil,
It is not possible to suggest any university because you have not given your percentile, your country choices, etc. There could be many possibilities. Check here instead, all the universities are good ones.

Keep note your budget, university's admission requirements etc before choosing.

Hi Joice,
Well, this will depend on a number of factors like your 12th grade, your overall profile and what were you doing all this while and if you gained work experience, if no then how will you justify the gap and so on. What you want to study, why you want to study, your career plans now, etc. must also be explained to the universities. You should start writing to some colleges and see their response.

Hello,
Majority of the Canadian universities require 75% and above, the required percentile vary with universities and programs. You may refer here for the specific requirements and apply accordingly, follow the timelines and apply on time.

Hello,
Every university accepts IELTS, TOEFL, PTE, etc. Applicants can take either of these tests. You may visit a couple of websites to have an idea. Additionally, for admission to a MBA program one must take the GMAT or the GRE. These tests are not waived and no recognized business school will accept a student without GMAT or the GRE.

Hello,
I am not quite sure which course you are interested for, there are many variants offered by Seneca. If you have completed your B.Com you should ideally look for post degree or a PG Diploma. You may see here for the relevant course and its admission requirement:

GRE and IELTS serve different purposes. IELTS (and TOEFL) is required to demonstrate English proficiency. GRE is a standardized test which is required if you are applying for admission to reputable universities like USC. So, you need to take GRE and anyone of TOEFL and IELTS.
