<p>It's a tricky one. Either do a rough translation based on conversion charts at your institution, and let them know on the application that it is an approximation, or leave the filed blank. I did the former. Because institutions differ so much, both in the US and abroad, they'll be more interested in where your university is ranked nationally, and your rank in the class. ie: Being in the top half of the best uni is probably a better indicator of achievement than finishing top 10% at middle of road one. </p>
<p>Also, your transcrips will have your raw score on, and the professors will know roughly what it means.</p>
<p>do not try translating your grades into a GPA format if it is not how it your grades are marked in your transcripts. </p>
<p>If you a are doing follow the American Education system, it is not useful because each educational system is based on how the students perform in those particular subjects and how the courseload is, so in case u get a B in any of ur subjects then it could actually be an A in the American system or a C or D or E depending on the system.</p>
<p>For example, an 80-85% in the Indian system is quite good, but if you convert it to the American system then it is a really bad score, so never convert your scores. While you apply the school sends a school transcript, school profile and grading limits which clearly indicate the courses that you take and how they are graded.</p>
<p>[joaoabreu] It is not just a matter of scale conversion. Letter grades in the US (A,B,C, etc.) are usually assigned to students based on performance relative to their peers in the class (i.e grading on a curve), whereas in many countries, the 0-10 scale denotes raw (absolute) grades instead. </p>
<p>Judging from your name, I assume you must be either Brazilian or Portuguese. In case you are Brazilian, you must be aware that in leading Brazilian universities like USP the top 1 % students in the class, especially in engineering and sciences, normally graduate with a course average slightly above 85. It is actually very rare for anyone to have a course average above 90. Those top 1 % students would probably have straight A's (i.e. a 4.0 GPA) in the US, but, in Brazil, because absolute grades are used, their equivalent grade is not 100. </p>
<p>Instead of converting your national grades into the GPA scale, the best thing to do IMHO is to supply your grades as they are , together with an official statement from your college/university indicating your rank in the class and how the grading scale should be interpreted. </p>
<p>Generally speaking, admission officials in the top graduate schools are familiar with the grading system in the major countries, such that they are normally able to interpret the meaning of a 1.0 grade in the German system or a first-class honours degree in a British-patterned system. Students who come from less well-known countries like Brazil or Portugal should supply admission officials with further information though to make sure that their grades are correctly assessed.</p>
<p>I heard there was a website somewhere that converts grades from any country. But I think grad schools requires a professional institute to do that for you. Anyway, send both.</p>
<p>From Columbia's website for International students:</p>
<p>My course grades on my undergraduate transcript are based on a different scale from Columbia’s. What can I do?</p>
<p>You need to get your transcript officially converted to the GPA scale by an appropriate agency (GPA is on a 0-4 scale) before submitting it. It is your responsibility to complete this conversion and the C.S. Dept. does not provide recommendations of which agency to use. For the online application, you can enter an approximate conversion of your percentage grade. A guide is given below:</p>
<p>Grade Grade Point </p>
<p>Approximate % Equivalent
A+ 4.0 90-100
A 4.0 85-89
A- 3.7 80-84
B+ 3.3 77-79
B 3.0 73-76
B- 2.7 70-72
C+ 2.3 67-69
C 2.0 63-66
C- 1.7 60-62
D+ 1.3 57-59
D 1.0 53-56
D- 0.7 50-52</p>
<p>That's a shockingly poor way of doing it from Columbia...</p>
<p>I have a 72% average at a British university. I'm ranked 2 or 3/50 in my class, and will in all probability graduate with the highest class of degree possible, but on that scale I have a B-.</p>
