what do marksheets tell us ?

<p>I mean when i look up to the universities’ websites to check whether I am good for getting in or not,
I just can’t understand how to convert my marks according to US and Canadian systems.
they say credits,courses,gpa and much more-some words I am hearing for the first time in my life!
I guess I might not even be considered for the admission and I am too frustrated about this :frowning:
does anyone know how to convert my marks into Canadian or US system of grading ?
any help will be appreciated.
thanks.</p>
