Liica, relax :) These grades do not disqualify you from graduate school admission in the United States. While the most elite graduate schools in the United States (Harvard, Stanford, etc.) usually require near perfect undergraduate GPA's, your grades will allow you to be very competitive when applying for the majority of American graduate schools. Your undergraduate GPA is just one of many factors graduate schools will consider during the admissions process. Graduate schools will also consider your extracurricular activities, professional experience, and test scores. If you are determined to attend graduate school in the United States, then my advice is to (1) continue earning the best grades possible, (2) find ways to increase your extracurricular/professional qualifications, and (3) start researching the admissions requirements of the specific programs in which you are interested.

In the USA, a "C" (2.0) is considered average. A 4.0 is the best you can get (unless you are doing advanced placement, which is graded on a different scale). Converted to the American scale, your grades are: Semester 1: B Semester 2: B+ Semester 3: B Semester 4: B Semester 5: B Well done!

Really Richard? That's a surprise for me. I thought the average to get into a school was 3.50

Liica, Those are all very good grades. They are above average. You could get into any school in the USA.
