Yes, as everyone else has said you need to understand how your school weights classes. Weighting just means you get a bump in your GPA for taking certain classes. For instance, an “A” in a regular math class might be worth a 4.0 while as “A” in an AP math class might be worth a 5.0. If you didn’t take any classes that give you the bump in your GPA, your weighted and unweighted GPA will be the same.
Every school handles there grading and weighting differently which is why colleges are often mainly interested in unweighted GPAs. At my D’s high school honors classes were not weighted, only AP classes were. They also take into account each schools grading system. At my D’s high school they did not grade an A as 90% in the class, a B as 80%, etc. I think to get an A you needed a 95% (to get a 4.0) and a 93 for an A- (to get a 3.67).
Your school handbook probably explains exactly how grading at your school works and you can probably find it online.
