GPA help?

<p>I am on spring break so I cant really ask my counselor. But on my transcript there is an average out of 100. Lets say my transcript says 89%. Do I put this number on the GPA part of the Common app? or do I have to wait for my school to calculate it out of a 4.0 scale? My School does final grades by adding 5 points to the final grade. Lets say AP Chemistry was a 75. the transcript would say an 80. So is the unweighted GPA a 2 or 3? is the weighted GPA a 3 or 4? What is a Good GPA for top unviersities? I visited Boston University and they told us that the average grade is an A- (3.7) GPA. I dont know whether to call bluff because on my School Navience it saw that the average from my school is an 82 more or less.....sorry for all the questions!</p>
