I agree with others who raise the concern that a 3.7 unweighted is typically not top5%, though your school could have very strict grading. Talk to your guidance counselor about where your general rank is. Schools that do not “rank” almost always send colleges a school profile that indicates a general range of gpas in the class, with some listing a median or highest gpa, or the %above a certain cutoff. Hence, colleges will be able to approximate your rank. Your guidance counselor should be able to provide you with a copy of the current senior class profile and at least that will give you some idea, in addition to asking where you stand now.
