IELTS

Hi Hiren,
To be eligible for MBA in HEC Montreal, applicants must have a minimum of 3 years work experience. Additionally you must take GMAT or GRE. With the current profile you are not eligible, unfortunately. You can consider doing the M.Sc program,work experience is not required but you still need to take GMAT or GRE. Do note that M.Sc with a specialization in finance is offered only in French by HEC Montreal. Would urge you to go through the website firstly to have a clear understanding.
Good Luck, feel free to revert if there is anything else you need to know.

For post graduate courses it is preferable to have at least 6.5 overall bands in IELTS. Please note that with your IELTS score many colleges might still offer admission, but the visa officers may reject your student visa as college admission and visa are two different processes. Even if you qualify according to the college's criteria keep in mind the visa requirements.

SAT is a standardized test for Universities admission in US which tells Universities about the college readiness and students' critical thinking skills. IELTS is only taken by students in non english speaking countries. It tells colleges that a student is fluent in English and will be able to understand the course instructions etc. in the college.

Go for TOEFL and get a score of at least 110 to be considered in the top universities. Rather than taking SAT you should go for ACT which is equally acceptable as SAT in all Universities. The format of SAT has recently changed and hence there are not many resources to prepare.

u should give TOEFL and gre.cuz IELTS is for countries other than usa

IELTS score requirements vary with programs and universities. Pallavi already mentioned the requirements so you must check with the universities directly before applying. The higher the scores the better.

Hi Arshdeep, you will be the best person to answer your question, nobody else would know what you are aiming for. If you have decided where to study you must decide what to study as well. Would also like to inform you that Germany is a good choice for engineering and Science quite contrary to your field.
Go through the DAAD website, they have the requirements listed. You must have an outstanding academic track record and an IELTS of 6 to 6.5 or higher. Fluency in German language will be required if you are looking for undergraduate studies.

Please mention which course you wish to pursue in Canada? You can get a student visa only if you are admitted for a course first.

Hello, apply to the universities, that would be a basic answer. If you haven't decided where to study please select the universities, narrow down your university choices and report your test scores to these. Check wic university requires what scores, do they have a minimum requirement! The application process is online and simple, visit websites for documents you need to upload alongwith. Keep track of the deadlines most importantly.

Hi,
ELICOS programmes are meant for international students requiring English language training before pursuing studies in Australia. Applicants not meeting TOEFL or IELTS score requirements can also enroll into a ELICOS prorgamme to qualify for English language requirements. You must contact with the concerned college for IELTS requirements and ELICOS. Every college have different requirements and they will guide you accordingly according to their requirement.
