<p>Hello,
I’m aware this may be a silly question, but I’d like to know wether the GPA average takes into account grades of all 4 years.</p>
<p>Also, here in Brazil the so-called high school has only 3 years. So would the last year of “junior high” here be regarded as the freshman year in US?</p>
<p>You can compute your GPA any way you like - you’ll just have to be very explicit about what went into the computation. I used as my GPA the official GPA computed by my school, which only takes the last two years into account.</p>
<p>That being said, US colleges still want to see grades from the last 4 years of your secondary education (i.e. the most recent 3 years if you are still in school). Colleges who actually use GPA numbers normally re-compute GPAs according to their own rules to make comparisons possible.</p>
