Polish education system and registration for SAT

<p>I would like to register for SAT and I have a huge problem - in Poland we don't have something like GPA.
We have only marks: 1(the worst) to 6(the best) from the all school subjects and a behaviour, nothing else.
Sometimes teachers want to compare us, in this case they calc average e.g. 4,25 but it isn't important and on the school certificate there are only marks.
We don't have stats(like GPA or the class rank) .
What I should choose in SAT registration form?</p>

<p>My second problem is fact that I am in penultimate class in the high school and I am 18 years old(in Poland when I've begun school I had to be 7 years old not 6). It is 12th grade or 11th?</p>

<p>I believe what you’d do here is either leave that spot blank, or, if you’re really gung-ho, try and convert your 1-6 scale to a 0-4 scale used in America.</p>

<p>To your 2nd question, yes, you would mark 11th if that is traditionally the 2nd to last grade in your school.</p>

<p>Actually, here’s a useful site that would show you how to convert the numbers to a US GPA (A= 4, B=3, C=2, D=1, F=0) <a href=“Scholaro Grade Conversion”>http://www.foreigncredits.com/resources/grade-conversion/&lt;/a&gt; (select Polish, Secondary)</p>

<p>Thank you very much for your response. </p>
