<p>Your guidance counselor needs to explain the grading scale, indicating what percentage of a class gets 4.3+, 4.0, 3.9, 3.8, 3.7, etc, etc, etc. Are there several valedictorians or just one, for example? Most Florida schools are on 5.0 scale, with +1 to classes that are AP/IB - for you, it would be IB, A Level, or equivalent classes.
Look on the International students forum for “how do you explain grading?”</p>
